        <description>Astronomers have many different methods for measuring the age of various objects in the universe, and they all support ages of billions of years, not thousands. Even if the assumptions of one or two methods were faulty, it is highly unlikely that all of the methods would be affected.</description>
        <content:encoded><![CDATA[<p>The dynamic changes and developments in the universe have been going on for a long time. In chapter 5 we described how geologists, over the past three centuries, have accumulated many kinds of evidence from rocks that the earth is billions of years old. In a similar fashion, over the past century astronomers have studied planets, stars, and galaxies and have found many strands of evidence that the universe is billions of years old. This consensus of astronomers is based on many independent measurements and has stood the test of time, a good indication that these results are reliable. In this section we’ll describe some of this evidence for the great age of the universe.</p>

<h3>Evidence from the Size of the Universe</h3>

<p>We’ve already discussed the vastness of the universe earlier in this chapter. We noted that the most distant galaxies are over 10 billion light years away, indicating that the light left these galaxies over 10 billion years ago in order to reach us today. The straightforward interpretation of these data is that the universe must be at least 10 billion years old.</p>

<p>While some people have argued that perhaps these galaxies aren’t really that far away, all of the methods used to measure distance agree that galaxies are billions, not thousands, of light years away. Others have argued that perhaps the light moved much faster when it first left these galaxies, so that it could reach us in much less time than 10 billion years. But this idea conflicts with other data that we have. As described in Chapter 3, ample evidence supports the idea that physical processes such as quantum mechanics and electromagnetism function the same way in distant galaxies as they do on earth. Those physical processes depend on the speed of light and would look very different if the speed of light had changed. Instead, they look the same in distant galaxies as they do on earth, indicating that the speed of light has been constant over the history of the universe.</p>

<h3>Evidence from the Moon and Planets</h3>

<p>Studies of the Moon and planets also give evidence for great age. Geologists can use some of the same methods to measure the age of rocks on the Moon, Venus, and Mars as they use on Earth. That’s because the asteroid collisions, volcanoes, and erosion they observe on Earth also occur on the Moon and planets. Photos taken by spacecraft while orbiting Mars show channels and gullies on the planet’s surface. Similar channels on Earth are usually made by flowing water. Yet there is no liquid water on the surface of Mars right now.</p>

<p>What does this have to do with age? It is evidence that Mars was much different in the past than it is today. The atmosphere used to be much thicker and warmer, similar to Earth’s, but now it is much colder and thinner. This dramatic change in planet-wide climate took millions or billions of years. Thus the rocks testify that the planet Mars must be at least this old.</p>

<h3>Evidence from the Orbits of Asteroids</h3>

<p>The orbits of asteroids also show evidence of a long history. When an asteroid is discovered, its path through the sky shows its orbit around the Sun. Once astronomers know the orbit of an asteroid they can calculate its orbit in the past and into the future to see whether it will hit the earth. By calculating the orbits backward, astronomers have found several asteroids that converged at the same location several million years ago. Apparently two larger asteroids collided at this spot and shattered into the smaller asteroids we see today. If God had created asteroids just a few thousand years ago, why would he have put them in orbits that suggest a collision several million years ago? The evidence clearly points to a long history for asteroids.</p>

<h3>Evidence from Meteorites</h3>

<p>Radiometric dating is used to study rocks on Earth as well as rocks from elsewhere in the solar system. Studies have been done on the rocks that astronauts brought back from the Moon and on asteroids that have fallen to Earth. As with Earth rocks, scientists use multiple radioactive isotopes to cross-check age measurements. At least three different isotopes have been used to measure the age of Moon rocks, and at least five different radioactive isotopes have been used to measure the age of meteorites. The results all agree: the oldest Moon rocks and asteroids are 4.6 billion years old. This is our best measure of the age of the solar system as a whole. The universe itself must be at least this old.</p>

<p class="caption-center"><a href="http://apod.nasa.gov/apod/ap120819.html" target="_blank"><img alt="" src="http://biologos.org/uploads/static-content/m72_hst_4114.jpg" /></a></p>

<h3>Evidence from Star Clusters</h3>

<p>Another important measure of age in the universe comes from star clusters. Because all stars in a star cluster form in the same nebula at about the same time, they all have about the same “birthday.” But they don’t all have the same lifespan. High-mass stars burn bright and fast like a “flash in the pan,” while low-mass stars burn slowly and steadily. Consider how this will look in a star cluster. A cluster starts with many stars with the same birthday but of all different masses. Over time the high-mass stars die off first, leaving behind the low-mass stars. This means that if many high-mass stars are present, the cluster must be young because they haven’t burned out yet. If most of the stars are low-mass, the cluster must be old. Careful studies of star clusters show that some clusters are younger and some are older, with the oldest ones having an age of about 12 billion years.</p>

<h3>Multiple Lines of Evidence</h3>

<p>The most distant galaxies, the planets and asteroids of our own solar system, and the oldest star clusters <em>all</em> are several billion years old. Astronomers have many different methods for measuring the age of various objects, and they all support ages of billions of years, not thousands. Even if the assumptions of one or two methods were faulty, it is highly unlikely that all of the methods would be affected. Like the geologists in the 1700s, astronomers today have found multiple lines of evidence against a young earth and young universe.</p>

<p>It may seem as though we are once again describing a conflict between science and theology. Scientific results that indicate great age do conflict with the Young-Earth Interpretation of Genesis 1 discussed in chapter 5. But remember that in chapters 5 and 6 we presented many other interpretations of Genesis 1; several of these are <em>not</em> in conflict with the great age found in the book of nature. In chapter 6 we also explained why we believe that the best biblical scholarship, quite independent of modern science, indicates that Genesis 1 was never meant to convey scientific information to the original audience. Its intent for the first listeners, and for us, is to teach the <em>who</em> and <em>why</em> of creation, not the <em>how</em> and <em>when</em>. Taken in this context, there is no conflict between Genesis 1 and the astronomical evidence for great age.</p>

        <title>Exploring Baby Galaxies with Charles Steidel</title>

        <description>No one need ask: “Were you there?” Chuck Steidel has tapped into nature’s own motion picture of past events, now showing in the present. Anyone who cares to view it can now see for himself what was and wasn’t there, at various stages of the deep past.</description>
        <content:encoded><![CDATA[<p>When I visited Caltech astronomer Chuck Steidel in 1996, he had recently discovered a method to fill in the enormous knowledge gap between our observation of modern galaxies and the universe’s first light (the cosmic microwave background radiation). For 20 years, astronomers had searched diligently—but unsuccessfully—for a way to single out a population of the earliest galaxies. Steidel had developed a method that proved itself capable of doing just that, so that today it continues to give astronomers the world over the data they need to learn how galaxies evolved.</p>

<p>As is the case in many fields, astronomers are trying to settle questions that the general public thinks little about, often because laypeople are still coming to grips with much more basic questions such as Did the universe appear—poof—all at once or did it evolve into its present state?</p>

<p>These are questions where science crosses into—and sometimes crosses swords with—religion. For many who take an anti-evolutionary stand as a matter of spiritual principle, the word <em>evolution</em> should not be applied to anything having to do with creation, cosmic or otherwise. Yet, if an evolving universe implies a beginning (and it does, for relativistic reasons), science has taken a tremendous leap toward rapprochement with Christian faith on the matter of creation. Traveling backward in time with their shrinking subject, cosmologists can only watch the cosmos disappear at the beginning, pointing to a universe that came out of nothing—a universe that wasn’t there.</p>

<p>No one need ask: “Were you there?” Chuck Steidel has tapped into nature’s own motion picture of past events, now showing in the present. Anyone who cares to view it can now see for himself what was and wasn’t there, at various stages of the deep past.</p>

<p>While other astronomers at first assumed that larger telescopes would be necessary before finding truly primeval galaxies, Steidel began finding dozens of them—and today, thousands of them. His method, called ultraviolet dropout, is based on the fact that intergalactic hydrogen gas absorbs the ultraviolet light of the most distant galaxies, causing them to disappear when seen through an ultraviolet filter. Steidel identified early galaxies that are present in pictures of the cosmos when viewed through red and green filters, but that aren’t there when viewed through an ultraviolet filter.</p>

<p>Visual evidence for a universe that isn’t there starts with the observation of galaxies that aren’t there.</p>

<p>“The way that people have looked for these in the past tended to be looking for particular, spectacular fireworks of stars going off all at once,” Steidel told me. He was only 32—a young-looking 32—and could have passed more easily as a student than as a professor as he talked with me in his Caltech office, surrounded by Hubble Deep Sky images. “So they were looking for relatively rare events, using narrow-band filters tuned to find an emission line that comes from hydrogen atoms. And you have to have the filter exactly tuned to that wavelength to see it.”</p>

<p>“And I’ve heard it’s like trying to find a needle in a haystack,” I offered.</p>

<p>“It’s much more difficult.”</p>

<p>“So rather than try to find something that&nbsp;<em>stands</em>&nbsp;out you’re trying to find something that&nbsp;<em>drops</em>&nbsp;out?”</p>

<p>“That’s correct. It’s a very simple technique, where we take pictures through different filters, very deep images of the sky with CCD detectors, and we take three filters, and we look for objects that are present through two of those filters, and they completely disappear in the third. And the reason they disappear is because they’re at a high redshift.”</p>

<p>The high redshift denotes greater distances—and earlier periods, because of the time required for light to reach us from those greater distances. These young galaxies contain young, hot stars, emitting strongly in the ultraviolet. However, ultraviolet radiation from the most distant galaxies is absorbed by a greater amount of intervening hydrogen gas along the way. Today, Steidel uses the 200-inch Hale Telescope at California’s Palomar Observatory to find these primeval galaxies with his ultraviolet dropout technique, then flies to the 10-meter Keck telescope in Hawaii to measure their redshift, which corresponds to their distance and time period.</p>

<p>And what do these galaxies look like?</p>

<p>“We actually think we’re seeing the central bulge regions of galaxies forming,” said Steidel, “that is, the round part in the middle of a spiral or an elliptical galaxy, where you expect all of the star formation to be happening in a relatively small region. And those parts of galaxies we see today are also the parts that we think are the oldest stars in those galaxies.”</p>

<p>“And you’re saying that modern galaxies have the oldest stars in the bulges, is that right?”</p>

<p>“That’s right …. It’s still somewhat controversial. But there isn’t any doubt that we’re finding a number of things that match fairly closely to the number that you would expect to find if you were looking at the progenitors of the present-day, bright galaxies.”</p>

<p>Steidel’s galaxy surveys have shown that galaxies were already arranged in clusters at that early time. But the individual, primeval galaxies lacked the characteristics of today’s spirals and ellipticals. More recently, Steidel has focused on a slightly later period, from about 10 to 12 billion years ago, when star formation appears to peak. If seeing is believing, then, as Steidel says, the universe “has absolutely changed with time.” His methods have helped astronomers identify populations of galaxies at various stages, where their differences from one to another are unmistakable.</p>

<p>In the years ahead, telescopes beyond our obfuscating atmosphere, like NASA’s James Webb Space Telescope (collecting six times as much light as the Hubble), may begin to give us glimpses of the “Dark Ages,” when the first galaxies began to form. As our improving technologies bring us closer to the beginning, they will lead people to ponder, once again, what happened before&nbsp;<em>that</em>.&nbsp;</p>

<p>In my interviews with researchers, I usually bring up such crossover questions when the scientists or their studies naturally suggest them. But I worried that I’d crossed over too clumsily into this territory with Steidel when I asked him what he thought about a universe that appeared to come into being out of nothing.</p>

<p>He hesitated and said, “What happened before, you know, it’s …” and his voice trailed off.&nbsp;</p>

<p>Finally I suggested: “<em>Something</em>&nbsp;must have happened before.”</p>

<p>“I think about that extremely rarely.”</p>

<p><em>Shoot, I’d gone too far</em>, I thought.</p>

<p>But then he added: “On the other hand, I do have a very wide appreciation for whatever put things there—because it’s just the greatest thing to go out on the catwalk around the dome, in the middle of the night, and just look up there, or look at a picture of the Hubble Deep Field, and see all the things that are out there, and—you know— it’s a beautiful universe out there.”</p>

<p>Indeed, come to think of it, the way it all came together may be an even more impressive fact to ponder than the fact that at one time, that is, before time, the universe wasn’t there.</p>

        <title>Hydrology of the Bow River</title>
        <link>http://biologos.org/blog/hydrology&#45;of&#45;the&#45;bow&#45;river?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>There’s a word beneath the water, and the Bow River belongs to God. Have you been listening?</description>
        <content:encoded><![CDATA[<blockquote>"All the rivers run into the sea, yet the sea is not full. To the place where the rivers flow, there they flow again." - Ecclesiastes 1:7</blockquote>

<p>“This is 2,300 year old wisdom from the Book of Ecclesiastes that seems to very concisely understand the water cycle. That water evaporates from the ocean, gets stored in the atmosphere via clouds, comes down as snow or rain, and when it comes down on the mountain it’s often stored there, as snow is gathered via groundwater, streams, and rivers, and then through the river, returns to the ocean, again. What a beautiful, complex, interdependent, wonderfully mysterious way of providing water, life to the land … But what does this beautiful system teach us, Father, Son and Holy Spirit, about who we are? What is your word, God, about this river, that runs through the center of where we live?”</p>

<p>In this sermon, Pastor Jon Van Sloten of New Hope Church in Calgary, Alberta, describes how he set out to learn where the water from the Bow River, near their home in the Rocky Mountains, actually comes from. He interviewed scientists who study hydrology and have learned a curious truth about how this particular river keeps a steady flow the full year round. This modulating geophysical “safeguard,” which allows the Rocky Mountains to hold water and let it out at a slow trickle rather than a deluge during the annual snowmelt, speaks to Van Sloten of God’s grace at work in the world—grace we can’t see with the naked eye, but is there all the same.</p>

        <title>Off with Their Heads</title>
        <link>http://biologos.org/blog/off&#45;with&#45;their&#45;heads?utm_source=RSS_Feed&amp;utm_medium=RSS&amp;utm_campaign=RSS_Syndication</link>

        <description>The Queen had only one way of settling all difficulties, great or small. “Off with his head!” she said, without even looking round</description>
        <content:encoded><![CDATA[<blockquote><strong>The Queen had only one way of settling all difficulties, great or small.<br />
“Off with his head!” she said, without even looking round.</strong><br />
<p style="text-align:right;">Alice in Wonderland, by Lewis Caroll</a></blockquote>
<p>Theology once held a seat of high regard among the sciences.  During the Middle Ages theology was the Queen of the Sciences, and it sat enthroned at the core of academic studies throughout Europe.  Many of the great European universities developed from the cathedral schools where theology was the nucleus around which all other study revolved and found its meaning.</p>

<p>The reason for this position of favor was that theology was discussion about – or the study of – God himself.  In God, believers found their purpose and very existence.  Therefore, God was not a position to be reasoned to; rather, reason flowed from one’s understanding of who God is and his relationship to humanity.  </p>

<p>As Queen, theology’s function was not to discover all the answers herself but rather to encourage the other subjects – her subjects – to pursue truth.  Math should discover that 2+2=4; biology should discover the mechanism of creation; psychology should discover the role of parent bonding in childhood development; but it was the role of the Queen to give meaning to the truths of her subjects.</p>
 
<p>In other words, 2+2=4 neither proves nor disproves the Creator, but theology – a profound belief in the Creator – sees the beauty in the ordered world around us.  Theology and math are not the same.  They answer different questions.  But they are not completely separate answers; together they form a more complete answer to each of their individual questions.  To quote Stephen Jay Gould, they are “nonoverlapping magesteria” to be certain, but they are also “interdigitating in wondrously complex ways along their joint border.  Many of our deepest questions call upon aspects of both for different parts of a full answer” (Gould, “Nonoverlapping Magisteria,” <em>Natural History</em> 106 (March 1997).  </p>

<p>It is unfortunate that Gould’s later explanation of these nonoverlapping magesteria left so little room for theology; in a sense, banishing the Queen almost completely to the hinterlands of the academic kingdom.  The image of these nonoverlapping magesteria “interdigitating in wondrously complex ways,” however, is still worth considering.  This image serves as a reminder that one should not reason from God or theological perspectives to mathematical principles or scientific theories anymore than one should reason from mathematical principles or scientific theories to the existence of God or the non-existence of God.  In their “interdigitating,” however, in the beautiful harmonies between theology and the other sciences a fuller answer is given – an answer that provides not only facts but also meaning.  </p>

<p>Unfortunately, the history of theology’s reign through the ages is questionable at best.  The Queen far too often hampered instead of encouraged the pursuit of truth by her subjects.  Today, many put the Queen at direct odds with her subjects, and this has led to a comical and tragic caricature of theology in our current society – a Queen who settles all difficulties, great or small, with the same solution, without bothering to look around, and by yelling, “Off with their heads.”</p>

<p>As Christians, who care deeply for the pursuit of truth, we cannot – and must not – attempt to restore theology to a place of prestige by destroying the work of her subjects or by belittling the work of those who practice them.  We must not attempt to settle every difficulty between theology and the other sciences by calling for the heads of others to roll while we bury our own heads in the sand.  </p>

<p>Rather, as theologians, whether professional or lay, we must assist theology to ascend to her throne as Queen of the Sciences by encouraging the pursuit of truth in all fields wherever they lead, by humbly entering into discussion with her subjects concerning the truth they discover, and by proclaiming the Truth that gives meaning to all truth – Jesus Christ, our Lord.</p>

        <title>Scientists Tell Their Stories: George Murphy</title>

        <description>During his seminary education, Dr. Murphy also gained a deeper understanding of Luther’s theology of the cross, and he realized that it’s really the best way to approach the science and theology dialogue.</description>
        <content:encoded><![CDATA[<p align="center"><iframe src="http://player.vimeo.com/video/39214344?title=0&amp;byline=0&amp;portrait=0" width="533" height="302" frameborder="0" webkitAllowFullScreen mozallowfullscreen allowFullScreen></iframe></p>

<p>George Murphy notes that while the science and theology dialogue has grown considerably in the past 30 years, much of it remains at an academic level.  While it provides an important foundation, that alone is not going to do the job that the church needs it to do—to come out in Christian education in parishes, in preaching, in pastoral care, in the social action of the church.</p>
 
<p>During his seminary education, Dr. Murphy also gained a deeper understanding of Luther’s theology of the cross, and he realized that it’s really the best way to approach the science and theology dialogue.  The theology of the cross helps us deal not only with an issue like evolution, and but more generally with the whole question of how God acts in the world and how we know God.</p>
 
<p>Most science and theology dialogue is restricted to discussion of creation and origins.  But at the core of the Gospel of is not simply the doctrine of creation—it’s salvation, it’s the work of Christ in saving humanity and in saving the whole creation.</p>

        <description>In this excerpt from the book Delight in Creation: Scientists Share Their Work with the Church, astronomer Deborah Haarsma shares her excitement about recent findings about our universe from a Christian perspective.</description>
        <content:encoded><![CDATA[<p>A passenger settles in beside me on the airplane. We chat a bit about our destinations, and then comes the inevitable question: “So, what do you do for a living?” I pause a moment before answering. If I answer “astronomy,” I know my fellow passenger will perk up, comment that he has always loved stars, and ask a question about a comet or planet that’s been in the news. If I answer “physics,” he will shrink back, comment that he didn’t do well in physics in high school, and the conversation will quickly come to an end. My professional colleagues have noticed the same thing. We joke that if you want to sleep on the plane, just answer, “Physics!”</p>

<p>It’s true that physics sounds scary to many people, and it can indeed be a difficult topic to learn. Yet I’ve always loved physics (my degrees are in physics rather than astronomy), because of the way that mathematical equations can describe and predict so much of what we see in the world around us. One reason I got into astrophysics is because the universe contains so many bizarre situations that we can’t reproduce on earth, like ultracold, or extremely high density, or extremely high magnetic fields. It’s a fun challenge to figure out which physical process will be the most important when the situation is so dissimilar to everyday experience. But if the word “physics” makes you shrink in distaste or fear, don’t worry. For the rest of this article, we’ll focus on a more friendly topic: astronomy.</p>

<p>In the last decade or two, our knowledge of the universe has grown dramatically as many new telescopes and spacecraft have come online. In this essay, I’ve selected some of my favorite recent astronomy photographs to share with you. As a professional astronomer and a Christian, I feel God has called me to share these wonders with the Church. Many times, these new discoveries are presented without any mention of God, and sometimes in a context of overt atheism. I want to share these things with you in a Christian context, with God as their creator.</p>

<h3>The Milky Way</h3>
<p>Have you ever seen the Milky Way? If you live in a rural area, you may have seen it many times. If not, it may have been a dramatic surprise when you first saw it while camping or traveling. On a clear night out in the country, the sky is strewn with brilliant stars—many more stars than you can see under city lights.The faintest stars form a creamy, smoky band from horizon to horizon. Our galaxy contains billions of stars, and thousands of those stars are visible to the naked eye. The stars appear in a band across the sky because we are viewing our galaxy edge-on, like looking at the edge of a dinner plate.</p>

<p>When David looked up at the night sky over Israel thousands of years ago, he may have seen the Milky Way, or a comet, or simply the brilliance of the full moon. Whatever the sky looked like that night, it inspired him to sing:</p>

<blockquote>The heavens declare the glory of God; the skies proclaim the work of his hands.
Day after day they pour forth speech; night after night they reveal knowledge.
They have no speech, they use no words; no sound is heard from them.
Yet their voice goes out into all the earth, their words to the ends of the world. (Ps. 19:1-4a)</blockquote>

<p>The heavens are displaying the glory of God for all people to hear, proclaiming their message to people of every language, tribe, and nation. Just about anyone who looks up at the night sky feels a sense of wonder. Yet as Christians, we feel more than a vague sense of awe; we know the Creator of the heavens personally, as our own loving Father.</p>

<p>The heavens declare more than God’s glory. The universe is God’s revelation of himself to us, and teaches us about his character. As the Belgic Confession says about “The Means by Which We Know God,”</p>

<blockquote>We know him by two means: First, by the creation, preservation, and government of the universe, since that universe is before our eyes like a beautiful book in which all creatures, great and small, are as letters to make us ponder the invisible things of God: his eternal power and his divinity, as the apostle Paul says in Romans 1:20. Second, he makes himself known to us more openly by his holy and divine Word, as much as we need in this life, for his glory and for the salvation of his own. (Article 2)</blockquote>

<p>The natural world teaches us about God’s glory, power, divinity, faithfulness, extravagance, immensity, love, and other attributes. God’s special revelation in scripture is our primary place to learn of God’s character (Ps. 19 goes on to talk about special revelation in vs. 7), but the natural world can bring the message to our senses in a powerful way beyond mere words on a page. The Holy Spirit can use the natural world to get the message past our hardened or weary hearts. Nature illustrates these attributes in ways that enlarge our imaginations to appreciate afresh the glory of God.</p>

<h3>The Sun</h3>
<p>The Solar Dynamics Observatory was launched into space in 2010, the latest of several spacecraft to photograph the sun in detail. In Figure 2, the upper photo shows the face of the sun with a sprinkling of sunspots. The sun is powered by nuclear fusion reactions deep in its core which heat the hydrogen and helium gas till it glows. A sunspot is a place on the sun’s surface where the gasses are a bit cooler than the surrounding area, so that it glows less brightly and appears dark.</p>

<p>The lower photo in Figure 2 was taken the same day, but in X-ray light. X-rays are invisible to our eyes, but you have experienced them at the dentist’s office. There, the X-rays are produced by a machine, travel through the mouth, and are detected by film to reveal an image of your teeth. In this image, X-rays are produced by the sun, travel to the Solar Dynamics Observatory, and are detected by a camera to show an image of the sun. In X-rays, the sunspots are the <em>brightest</em> part of the image, not the faintest. If you look at the sunspot on the left edge, you can see bands of particles rising out of the sunspot in a looping path above the sun’s surface and falling back down on it. As the particles follow lines of magnetic field, they emit X-rays. The loops you see are not small—they are about the size of planet Earth! Because of modern spacecraft, telescopes, and cameras, we can see so much more in the heavens than what is visible to the naked eye. Thus, we are seeing more of what the heavens have to declare about God. In Psalm 19, David goes on to describe the sun:</p>

<blockquote>In the heavens God has pitched a tent for the sun. It is like a bridegroom coming out of his chamber,
like a champion rejoicing to run his course. It rises at one end of the heavens
and makes its circuit to the other; nothing is deprived of its warmth. (vs. 4b-6)</blockquote>

<p>If David had lived today, maybe he would have written about other properties of the sun, like the power of God as seen in nuclear reactions and looping magnetic fields. As it is, he makes two important points. One is the universal warmth of the sun, by which God provides for all life on earth. The other is the faithful path of the sun, day after day, unchanging year after year. In the book of Jeremiah, God promises his people that he will not break his covenant with them, any more than he would break his covenant with day and night and the fixed laws of heaven and earth (33:19-26). The sun is a persistent reminder, woven into our lives, of God’s faithfulness to his promises.</p>

        <title>Series: Biblical and Scientific Shortcomings of Flood Geology</title>

        <description>Gregg Davidson and Ken Wolgemuth seek to remove the stumbling block of the Genesis flood in this four part series. Though many believe in an ancient world&#45;wide flood, the evidence given does not hold up to geological scrutiny, but points rather to something regional instead. It is their hope that Christians will not walk away from faith in Christ simply because a global flood is not supported by science. Looking at natural phenomena like the Grand Canyon, salt beds, and fossil deposits, they reveal reasons for these deposits and structures while showing that their origin did not stem from a violent flood that covered the planet.</description>
        <content:encoded><![CDATA[<p class="intro">This is the first in a four part series taken from Gregg Davidson and Ken Wolgemuth's <a href="http://biologos.org/uploads/projects/davidson_wolgemuth_scholarly_essay.pdf" target="_blank">scholarly essay</a> "Christian Geologists on Noah’s Flood: Biblical and Scientific Shortcomings of Flood Geology".</p>

<p>As Christians and geologists, we frequently encounter people with stories of storm tossed and shipwrecked faith that started when they began to wrestle with apparent conflicts between science and the Bible.  The stories have a common thread. The Bible, they were told, clearly teaches the earth was created a few thousand years ago with life forms fashioned more or less as we find them today. Because the earth is very young, the incredibly complex sequence of rock, sediment, and fossils found on our planet must have been deposited in a very short period of time. Noah’s Flood, as the only plausible causal agent, was obviously a global and violent event.  Theories of an ancient earth and adaptation of life forms, they were further informed, have been constructed on flimsy evidence created by atheistic scientists searching for ways to expunge God from modern culture. But as these sojourners began to explore and understand the actual evidence for an ancient earth, they found themselves increasingly convinced of its legitimacy, and thereby increasingly questioning the veracity of their faith – many to the point of relegating Christ to just another wishful myth.</p>

<p>It is our conviction that these stories of strained or lost faith derive not from an inherent unwillingness to trust the Bible, but rather from misguided teaching on the message of Scripture. Those insisting the earth is young are not simply putting their faith in God’s Word, they are putting their faith in their own particular interpretation of that Word. As such, an entirely unnecessary stumbling block to faith is created, where faith in Christ first requires rejection of sound science.</p>

<p>As we have prayed and studied this subject, we have felt God’s call to speak out against this misplaced stumbling block. We are sensitive, however, to the fact that when scientists speak on issues of faith, there is a natural suspicion that science will be regarded as the ultimate arbiter of truth, and Scripture will have to yield whenever conflict arises. It is thus important for us to state here that both of us ascribe to the authority and inspiration of Scripture, the reality and necessity of Christ’s death and resurrection, the existence of genuine miraculous events, and the truthfulness of the Biblical historical narratives. In our understanding, science will never trump Scripture, but by virtue of science being a study of God’s natural creation, it may occasionally assist in our understanding of God’s written Word. Where this has occurred historically and has been accepted by the Church, the invariable result has been the abandonment of an interpretation of some secondary importance, without any change in our understanding of the intended central message.</p>

<p>This phenomenon is illustrated well by the 17th century clash between Galileo’s claims that the earth revolves around the sun, and the multiple passages in Scripture that appear to clearly present a static earth as the physical center of God’s natural creation. The Bible tells us repeatedly that the earth is fixed upon its foundations (Ps 93:1, 104:5) and the sun rises and sets (Eccl 1:5, Ps 19:6).  Within the context of the historical narratives (which we are not accustomed to interpreting in any figurative manner) we read statements about “the sun rising over the land” (Gen 19:23), and a miraculous event during a famous battle where “the sun stopped in the middle of the sky and delayed going down a full day” (Josh 10:13). Likewise in the Levitical law, we find commands to complete the Passover sacrifice “when the sun goes down” (Deut 16:6).</p>

<p>God’s people had interpreted these verses for thousands of years to be authoritative statements about both spiritual and physical realms, and 17th century believers understandably struggled with allowing science to alter traditional interpretations. If God says the sun rises and the sun sets, how could it be otherwise?</p>

<p>Fast forward a few centuries, and we are now somehow quite content to have allowed science to alter our thinking on these verses, without abandoning notions of inerrancy or inspiration. The reason is simply because it was eventually recognized that the primary message of these verses was never on the nature of nature, but on the nature of man and his experience with his environment and his God. Solomon and Joshua accurately recorded their experience from an earthly perspective (sun rising and setting), and David praised God for holding the earth fixedly in His hand (Ps 93:1, 104:5), without requiring a meaning of fixity in space. The central message of these verses was apparent to readers before and after Galileo. Only a secondary interpretation, likely never intended by the writers, was cast off after scientific advances.</p>

<p>So what is the issue regarding Noah’s Flood? The modern debate centers around two questions. Was it truly global in extent, and can the Flood account for the earth’s complex geologic record?  To address the first, it is worth being reminded of the Apostle Paul’s letter to the church in Rome where he makes a statement that “your faith is being proclaimed throughout the whole world” (Rom 1:8). Entire people groups existed at this time in China, Australia, and North and South America who knew nothing of the church in Rome. Though using wording that literally means the entire world population, Paul is clearly referring to the world known to him and his readers at the time.<sup>1</sup>  Paul speaks truthfully from his experience. Allowing for the possibility that Noah’s Flood encompassed all of known humanity without necessarily covering the entire planet is thus consistent with how other passages in Scripture are interpreted by Christians who believe the Bible is authoritative and trustworthy.</p>

<p>Our primary interest in this blog series is the second question, the widely promulgated notion that the Flood can account for the earth’s complex geology, and that all genuine Christians should accept this viewpoint.</p>

<h3>Notes</h3>
<p class="date">1. Many Biblical scholars define a <em>literal</em> interpretation as one that takes into account the literary genre, figures of speech, context, and author/audience perspective in deriving the intended meaning. By this definition, poetry and allegory are <em>literally</em> interpreted as <em>figurative</em>. In this blog and in our article, our use of <em>literal</em> conforms to its more common definition where a literal interpretation is one that adheres to the precise definition of words without figurative meaning and without requiring additional context to understand.</p>]]></content:encoded>

        <title>A Pastor&apos;s Approach to Science</title>

        <description>Since the sermon is the main component used to build the congregation’s collective approach to understanding how the church relates to the world, I want to take a few moments to lay out what has worked in my preaching and what has not when it comes to science, and more specifically, the subject of evolution.</description>
        <content:encoded><![CDATA[<p>In the United States the central task of most evangelical pastors is to exegete Scripture in ways that it continues God’s story (as fulfilled in His Son) in our present and personal lives. Such a task demands a comprehensive approach. We are not mere intellectual depositories, or we would be Gnostics. We are not summaries of moral right and wrong actions, or behavior modification would be all we need. We are not only spirit, or meditation/worship would be our exclusive activity. We have <em>bodies</em> and we reside in a physical world that is not only our environment, but a part of God’s ongoing revelation of Himself (Romans 1:20). </p>

<p>Is it possible to fully understand and practice Scripture without connecting with science? If science reveals God’s attributes, how can we fully relate to Him without some ongoing reference to the information revealed in scientific inquiry? Even more specifically, as preaching pastors, how many are we excluding if we ignore important facets of our congregations’ worldviews? </p>

<p>Now in a collaborative environment like this, it is easy to stay on an intellectual level. But we are pastors who are practitioners, so let me speak personally to get the discussion into the realm of the church world and what may or may not work for you. Some 27 years ago, while exploring whether or not to go to pastor Northland Church, I sensed I’d found kindred spirits when reading in its philosophy of ministry:</p>

<blockquote>People are not just to be understood as sinners but as beings greatly affected by the bodies and physical world they inhabit. </blockquote>

<p>How then would I best address that physical world in the context of understanding its value to our spiritual formation?</p>

<h3>Different Approaches to Scripture and Science</h3>

<p>Since the sermon is the main component used to build the congregation’s collective approach to understanding how the church relates to the world, I want to take a few moments to lay out what has worked in my preaching and what has not when it comes to science and more specifically the subject of evolution:</p>

<p>1.	I decided on a hermeneutical approach. How would God’s patterns in creation published in scientific findings inform my understanding of Scripture?</p>

<ul><li>I would not use the “Science and Faith are in conflict” (J.W. Draper/A.D. White<sup>1</sup>) approach, since I am neither a fundamentalist nor someone whom would wish to violate the spirit of those who penned Scripture who understood God to be over all the world, both hill and Temple (Psalm 24:1-10).</li>
<li>I would not use S.J. Gould’s<sup>2</sup> “Non-Overlapping Magisteria” approach, which “ghettoizes” both science and faith. To say one only answers “how” and the other only answers “why” is to miss the richness of both.</li>
<li>I would not use Pierre Teilhard de Chardin’s<sup>3</sup> or Ian Barbour’s<sup>3</sup> “Integration / Unity” approach, since such an approach requires extensive knowledge of both science and theology and almost inevitably leads to process theology.</li>
<li>I would use the “Dialogue” (W.G. Pollard<sup>5</sup>) approach, since it emphasizes insight and investigation rather than answers, thereby leading to a sense of wonder and worship. Such an approach minimizes the hubris of knowledge (that will almost certainly pass away) and the hostility toward different perspectives.</li></ul>

<p>2.	I decided on a related-referential model rather than an issue-oriented one.</p>

<ul><li>Any model chosen must fit the personal style of the preacher or it will become uncomfortable and soon unused. I am more the Columbo/sloppy trench coat, “Oh that reminds me…one more thing…” investigator rather than a “light bulb hanging over the head breaking down your resistance” kind of confronter. So I use science as “now what do you make of that?” kind of illustration rather than an argument for my perspective.</li>
<li>The model must also fit the personality of the church. In our church issue-oriented subjects must be taught in classes or small groups where people have the chance to question/comment in ways not usually done in response to sermons.</li></ul>

<p>3.	Our church has decided that being a witness of the incarnate Christ means engaging, and learning from, the world as it is presently.</p>

<ul><li>Following God’s example in Christ is entering into the world and serving in all its realms: spiritual, emotional, physical, and social.</li>
<li>Christ used the common knowledge people already had (much of it from nature) to reveal God.</li></ul>

<h3>Recognizing Cultural Perspectives</h3>

<p>Having laid out what seems like a tidy approach, I will now recognize the difficulties I have experienced, as a pastor, pertaining to evolution, for understandable but remediable reasons.  The church has a particular culture that prevents fully engaging science.</p>

<ol><li>Most in a congregation do not decouple or differentiate the belief in a philosophy of random and purposeless evolution from the instances of incremental improvements that may point ultimately to an Organizing Principal.</li>
<li>Most have not been taught the literary genre distinctions between the writings of Genesis 1 and a science textbook.</li>
<li>Most have not considered the possibility that Adam and Eve may not have been uniquely and separately physically created for their sole role in the beginning of human kind. They need alternatives involving figures that do not contradict the point of the narrative.</li>
<li>Most have not considered the complementary nature of the Biblical narrative of redemption out of death and the evolutionary one.</li></ol>

<p>To be sure, when a pastor addresses the alternatives, or even makes an explanatory reference using evolution, that pastor can expect a variation of this conversation I had with a parishioner (who walked out during a sermon) a little over a year ago:</p>

<blockquote>____________, I know I upset you with the reference I made to evolution. You have been listening to my teaching for many years. I hope you know by now how the high view of Scripture as the final source of truth and authority I hold and this church holds.

'Well, I thought I did but now I am not so sure,' answered this lady who has been trying to get Ken Hamm to our church for some years.

You know I would never do anything to lessen the importance of Scripture.

'Pastor, when you confess evolution, you not only make a liar out of Scripture, you become the reason young people are not following God and are living lives without regard to the Bible, and are in some cases committing suicide.'</blockquote>

<p>This woman is not an unintelligent person. She is a professional nurse and is leading in a mission organization. She was just scared. Happily, she is still in the church and has decided after some more reflection that maybe I do not want to lead young people into orgies and death after all.</p>

<h3>Summary Thoughts</h3>

<p>In 1632 Galileo warned his fellow believers of a trap they were walking into by resisting the conclusions of a scientific investigation: </p>

<blockquote>Take note, theologians, that in your desire to make matters of faith out of propositions relating to the fixity of sun and earth you run the risk of eventually having to condemn as heretics those who would declare the earth to stand still and the sun to change position--eventually, I say, at such a time as it might be physically or logically proved that the earth moves and the sun stands still.<sup>6</sup></blockquote>

<p>We would do well to be the church learning God’s truth as discovered by scientists, not resisting its discomfort or its perceived threat to our traditional interpretations of Scripture.</p>

<p>We worship a God of history, and references to our physical world fit well, given some time, into our metaphysical journey. One only has to look at the Old and New Testaments to see how central the elements of creation are to understanding the activity, and thus the “nature” of God. The references are not simply meant to be objective facts; they are to open the door to vistas beyond. If postmodernism has made us aware of the illusion of pure objectivity, then it has also taught us something of the value of pre-modernism, where the lines between the physical and spiritual are connecting points.</p>

<p>Of course nature is not prescriptive, nor does it present comprehensive pictures of God’s personality. One of the most intellectually capable scientists I know does not believe in God because of his observations of ants organizing slave colonies. It offends his sense of egalitarianism. Talk about making a mountain out of an anthill! Theologizing from particular scientific observations is hyper-interpretive.</p>

<p>Yet, as all creation was made by and for Him (Colossians 1:16-17), when it comes to the insights that may be offered by scientific information (especially evolution) it is difficult for those who have been given a modicum of faith not to see the possibility of:</p>

<ul><li>An Organizing Principle</li>
<li>An Orchestrated Similarity among the physical, personal, social, and spiritual realms</li>
<li>An increased ability and likelihood to respond to the outside world in ways that benefit all</li>
<li>Redeeming relationships involving sacrifice, not all of which are initially positive or intentional (Romans 8:28)</li>
<li>Problematic instances that would seem to negate the idea of a loving kind Creator may be a part of a more positive trend.</li>
<li>Greater confidence, as a result of faith, in uncontrollable circumstances being used for good eventually</li></ul>

<p>My goal as a pastor is to equip the saints in my sphere of influence to see Christ and to worship Him. If those in my influence only can see God in Scripture, then they are half blind. But if we together can help each other see the unfolding redemptive purposes of every realm - of scientific inquiry, of business practice, of artistic expression, of church/family support for every individual in every field of endeavor – then we will be not only 20-20 but 3-D in every direction!</p>

<p>Of course, such a result will require a more comprehensive approach in preaching. And such comprehension will require a continuing dialogue with those who can help us see the truth from different perspectives.</p>

        <content:encoded><![CDATA[<h3>How are the ages of the Earth and universe calculated?</h3>

<h4>In a Nutshell</h4>
Many independent measurements have established that the Earth and the universe are billions of years old.  Geologists have found annual layers in glaciers that can be counted back 740,000 years.  Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4.6 billion years.  Astronomers use the distance to galaxies and the speed of light to calculate that the light has been traveling for billions of years.  The expansion of the universe gives an age for the universe as a whole: 13.7 billion years old. <br />

<h4>In Detail</h4>

<h3>Introduction</h3>
<p>Astronomers and geologists have determined that the universe and Earth are billions of years old. This conclusion is not based on just one measurement or one calculation, but on many types of evidence.  Here we will describe just two types of evidence for an old Earth and two types of evidence for an old universe; more types can be found under <a href="#reading">Further Reading</a>. These methods are largely independent of each other, based on separate observations and arguments, yet all point to a history much longer than 10,000 years. As Christians, we believe that God created the world and that the world declares his glory, so we can’t ignore what nature is telling us about its history.</p>

<h3>Age of the Earth from seasonal rings and layers</h3>
<p>If you’ve ever seen a horizontal slice of a tree trunk, you’ve seen how a tree forms a new growth ring each year.   In years of drought, the tree grows less quickly so the ring is narrower; in good growing seasons the ring is thicker.  A tree’s age can be found by simply counting its rings.  By comparing the pattern of thick and thin rings to weather records, scientists can verify that the method is accurate.   This method can even be used on dead trees that fell in a forest long ago.  For example, the last 200 rings in the dead tree might match up with 200 rings early in the life of the living tree, so the two trees together can count back many years.   In this way, multiple trees can be used to build a master chronology for a forested region.   European oak trees have been used to build a 12,000-year chronology.<sup>1</sup></p>

<p>The annual ice layers in glaciers provide a similar method that goes back much further in history.  Each year, snowfall varies throughout the seasons and an annual layer is formed.  Like the tree rings, this method can be verified by comparison to historical records for weather, as well as to records of volcanic eruptions around the globe that left thin dust layers on the glaciers.   Scientists have drilled ice cores deep into glaciers and found ice that is 123,000 years old in Greenland<sup>2</sup> and 740,000 years old in Antarctica.<sup>3</sup>  These annual layers go back much farther than the 10,000 years advocated by the young earth creationists.  The Earth must be at least 740,000 years old.</p>

<h3>Age of the Earth and solar system from radiometric dating</h3>
<p>In your high school science classroom, you may have seen a large poster of the periodic table hanging on the wall.  The periodic table shows the types of atoms that make up the world around us.  An element in the periodic table can come in different flavors called isotopes.  Some isotopes are unstable, and over time these isotopes “decay” into isotopes of other elements.   For example, Potassium-40 is unstable and decays into Argon-40.   As time passes, a rock will have more and more Argon-40 and less and less Potassium-40.   Radiometric dating is possible because this decay occurs at a known rate, called the “half-life” of the radioactive element. The half-life is the time that it takes for half the radioactive sample to change from one element into the other.</p>

<p>Some isotopes have short half-lives of minutes or years, but Potassium-40 has a half-life of 1.3 billion years.  Radiometric dating requires that one understand the initial ratio of the two elements in a given sample by some means.  In this case, Argon-40 is a gas that easily bubbles out and escapes when it is produced in molten rock.  Once the rock hardens, however, all the Argon-40 is trapped in the sample, giving us an accurate record of how much Potassium-40 has decayed since that time.   So, if we find a rock with equal parts Potassium-40 and Argon-40, we know that half the Potassium-40 has decayed into Argon-40, and that the rock hardened 1.3 billion years ago.<sup>4</sup></p>

<p>It’s hard to find rocks on the surface of the Earth that have not been altered over time.  Most old rocks have been eroded by wind and water or submerged by continental plates.   The oldest reliably dated rock formation is in Greenland, where several different isotopes were used to find an age of 3.6 billion years.<sup>5</sup>   Scientists also recently dated zircon grains (which resist erosion) in Western Australia to 4.4 billion years old.<sup>6</sup> To find older rocks that haven’t been eroded, we need to look beyond Earth.  Meteorites are rocks from the solar system that have fallen to Earth recently and haven’t suffered much erosion.  Their pristine interiors give an age that dates back to their formation at the beginning of the solar system.  Nearly all meteorites have the same radiometric age, 4.56 billion years old.<sup>7</sup> Thus, the solar system, including the Earth, is about 4,560,000,000 years old.</p>

        <content:encoded><![CDATA[<p>At a press conference on July 4, 2012, and with 99.99994% confidence (5 sigma), CERN announced the discovery of a particle consistent with that of a Higgs boson (a.k.a. “the God particle”). This is very exciting for elementary particle physicists. It is also getting the attention of press and general public. But what is the Higgs particle, and what is its meaning? </p>

<p>It has been widely reported that the moniker “<a href="http://biologos.org/blog/naming-the-god-particle">God particle</a>” was not its originator’s first choice. Still, Leon Lederman, director emeritus of Fermilab and Nobel laureate for neutrino research, did accept the nickname “God particle” because the particle is “so central to the state of physics today, so crucial to our final understanding of the structure of matter, yet so elusive.”  “God particle” was quickly accepted by the press and general public because it seemed an appropriate title for a particle theorized to give mass to all elementary matter particles and the force carrying W and Z bosons.  Serving this mass-giving function since near the beginning of the universe, a Higgs <em>field</em> (more fundamental than the actual Higgs <em>boson</em> ) must necessarily exist everywhere in the universe and be unchanging. With an omnipresent and immutable field, analogies between the Higgs boson and God naturally developed within the press and the public—“God particle” became deeply rooted. Relatedly, the Higgs boson become an excellent source for theological analogies. (See for example <a href="http://www.telegraph.co.uk/science/8956938/Higgs-boson-the-particle-of-faith.html" target="_blank">this article</a>.) </p>

<p>Nevertheless, as physicists seek to emphasize, neither the Higgs boson particle nor its field have religious properties. Thus, elementary particle physicists are not fond of the “God particle” appellation.  In the opinion of Oliver Buchmueller, of CERN’s CMS group, calling the Higgs boson the “God particle is completely inappropriate. It’s not doing justice to the Higgs and what we think its role in the universe is. It has nothing to do with God“. As Pippa Wells, another CERN scientist expressed, “Calling [it] the God particle … confuses people about what we are trying to do at CERN”. (<a href="http://www.reuters.com/article/2011/12/14/us-science-higgs-god-idUSTRE7BC28H20111214" target="_blank">Source: Reuters</a>)</p>

<p>One alternate name for the Higgs particle that is used within the physics community is the “BEH” particle. “BEH” stands for Brout–Englert–Higgs, three of the six authors of 1964 papers that first proposed a mechanism for giving mass to elementary particles. In addition to Peter Higgs, the five other authors are Robert Brout and Francois Englert, and Tom Kibble, C.R. Hagen, and Gerald Guralnik. The process for giving mass to particles is thus sometimes referred to not just as the Higgs mechanism, but as the Brout–Englert–Higgs–Hagen–Guralnik–Kibble (BEHHGK) mechanism. (Saying all six names a couple of times makes it obvious why we most often only call it the Higgs.)</p>
 
<img src="http://biologos.org/uploads/static-content/cleaver_higgs_2.jpg" alt="" height="675" width="550"  />

<p>But issues of naming aside, what is the Higgs and why is it so elusive?  According to the Standard Model, the particles that compose matter (the quarks and leptons) are in a category called spin-1/2 particles. The force carrying particles (the photon, the W's, the Z, and the gluons) are spin-1 particles. What the physicists above proposed was the existence of a type of spinless, or spin-0 particle. Not only does the Higgs boson form its own class of particles, it also gives mass to itself and to all the other particles that have mass: to all of the leptons and quarks, and to the W's and Z bosons, but not photons or gluons. This set of relationships is shown in the image below, indicated by the lines connecting the Higgs to these other particles. There are no lines directly connecting the Higgs boson to photons and gluons because the Higgs boson does not interact with these force carrying particles and, thus, photons and gluons remain massless.</p>
 
<img src="http://biologos.org/uploads/static-content/300px-Elementary_particle_interactions.svg.png" alt="" height="215" width="300" style="display: block; margin-left: auto; margin-right: auto" />

<p>But the story of the Higgs particle actually begins with the associated Higgs field, an invisible field (something like a generalization of an electric field) that has a non-zero, constant value everywhere throughout the universe. This Higgs field continuously interacts with all matter particles and the W and Z force carrying particles. Matter and massive force particles are slowed down as they move through the Higgs field, just as are balls rolling through thick mud. The Higgs field is sometimes described as a “cosmic molasses”. Different particles interact with the Higgs field to varying degrees—those interacting more, are slowed down more, those interacting less are slowed down less. Slowing down more equates to acquiring more mass. If not for the Higgs field, all particles would be massless, zipping through the universe at the speed of light. The universe would be without structure—no galaxies, no plants, no life. Without the Higgs field, not even atoms could have formed.  </p>

<div class="see-also">It should be noted, however, that the majority of the mass of protons and neutrons (and thus of atomic mass) does not come from interaction with the Higgs field. Each proton and neutron is composed of three quarks, which do receive their mass from their interaction with the Higgs field. However, the masses of protons and neutrons are much greater than the sum of their constituent quarks and are a result of the additional mass contribution from the binding energies of the “trapped” quarks. </div>

<p>It was theoretically possible for elementary particles to have mass without needing to acquire it through interaction with a Higgs-like field. However, as the standard model of elementary particles developed in the 1950’s and 1960’s, elementary particle theorists realized that if particles had their own innate mass, rather than acquiring it, many beautiful symmetries of particle interaction equations would be broken. To keep the beauty and symmetry in the theory was the essential reason the BEHHGK mechanism was developed, which immediately led to the prediction of Higgs bosons. </p>

<p>When there is enough external energy in a given volume, the Higgs field also produces Higgs bosons. But the Higgs bosons are very unstable and quickly decay. This is the process that enabled the discovery of the Higgs boson at CERN. At CERN, protons are accelerated to high energies via electric fields and directed in circular paths via magnetic fields. The protons then collide and release large amounts of energy. When sufficient energy is released in a collision, the Higgs field can use this energy to produce Higgs bosons. The Higgs bosons quickly decay leaving evidence of their existence through particular combinations of leftover particles that they have decayed into.  Among those predicted by the mathematics of the Standard model are the muons and electrons identified by the CERN experimenters. The image at the top shows the identities and paths of particles produced in one of the CERN proton-proton collisions whose results fit with what would be expected from the decay of a Higgs boson.   </p>

<img src="http://biologos.org/uploads/static-content/cleaver_higgs_5.png" alt="" height="266" width="550"  />

<p>For a proton-proton collision at the CERN LHC, the above diagrams show both the dominant modes for creation of a Higgs with a mass around 125 GeV, and the two dominant decay channels (modes). The creation mechanism (shown schematically in the left half of each diagram above) involves virtual gluons, the carriers of the strong nuclear force (represented by squiggly purple lines) from the protons. The gluons fuse into a virtual top quark loop (medium blue triangle), which then emits a Higgs boson (squiggly yellow line).  The top quark couples more strongly to the Higgs than any of the five other quarks, so the top quark contributes the dominant loop.</p>

<p>The Higgs boson then dominantly decays into either (i) 2 gamma ray photons (the squiggly green lines) via another intermediate virtual top quark loop or a virtual W gauge particle loop (dark blue triangle), or (ii) two Z0 gauge particles (squiggly dark blue lines), which each then decay into a lepton (specifically an electron or a muon)/anti-lepton pair (light blue lines). </p>

<p>The likely discovery of the Higgs boson, and its implied existence of the associated Higgs field, is an amazing success for CERN. Past research and experience at Fermilab and by elementary particle physicists throughout the world also contributed to the discovery. The Higgs boson was the remaining particle in the Standard Model of Particle Physics to be found. With it, the Standard Model is in some sense complete. (Nevertheless, many questions about the Standard Model still remain—many inspired once again by beauty and symmetry. In particular, several numeric values associated with particle masses and interactions could only be experimentally measured, as with the Higgs, and not predicted from the Standard Model.) </p>

<p>With the apparent success of these experiments and seeming confirmation that the physical universe is, indeed, reflected by the complex and beautiful mathematics of the Standard Model, the international physics community is eager to keep delving deeper into the structure of creation.  In addition to trying to verify that the 125 GeV particle is, indeed, the Higgs spinless particle and not some more exotic, new particle, CERN physicists are simultaneously seeking to discover an entire new class of particles, resulting from a theorized symmetry called supersymmetry. Discovery of the associated particles, if they exist, will likely take a few more years. For these discoveries we can only wait in anticipation.</p><br></br>

        <description>The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity?  Is there actually any theological or religious significance in Higgs physics at all?</description>
        <content:encoded><![CDATA[<p class="date"> The image above describes an "event" (proton-proton collision) recorded in 2012 with the CMS detector at CERN's Large Hadron Collider. According to CERN, "the event shows characteristics expected from the decay of the SM Higgs boson to a pair of Z bosons, one of which subsequently decays to a pair of electrons (green lines and green towers) and the other Z decays to a pair of muons (red lines). The event could also be due to known standard model background processes. ATLAS Experiment © 2012 CERN </p>


<p>Judging from the flurry of headlines over the past week, one might be tempted to think that proof positive of God’s existence (or lack thereof) had just appeared out of a 27-km-tunnel buried beneath the Swiss-French border. This frenzy of news headlines and blog titles hailed the recent news that CERN’s Large Hadron Collider has discovered a brand new particle of a mass of 125-126 GeV, which is assumed to be the Higgs boson, or the so-called “God particle.” The discovery of the Higgs boson would certainly be a breakthrough for particle physics and cosmology, but would such a finding also radically redefine theology’s understanding of God or challenge the existence of such a deity?  Is there actually any theological or religious significance in Higgs physics at all?</p>

<p>The short answer is “no,” which becomes apparent when one considers the widely-reported story of how it got named. In 1993, Nobel Laureate physicist Leon Lederman, along with science writer Dick Teresi, wrote a book detailing the history of particle physics starting with Pre-Socratic Greek philosophy Democritus and culminating with the hunt for the Higgs boson. Until this latest discovery, the Higgs boson was the elusive final missing piece of the puzzle known as the Standard Model—a collection of the fundamental particles that constitute our universe and the complex and mathematically-sophisticated relationships between them. Considering how incredibly difficult finding the Higgs boson was proving to be, Lederman wanted to name the book after that “goddamn particle,” according to some of his collaborators. His editor, however, would not allow it and so the name was shortened to “The God Particle: If the Universe Is the Answer, What is the Question?” And thus ‘the God particle’ was born, carrying with it more than enough social baggage for such a miniscule particle.</p>

<img src="http://biologos.org/uploads/static-content/Zosia_Krusberg.jpg" alt="" height="340" width="250" style="float:right;margin:0px 0px 0px 10px;"  />

<p>Particle physicist Dr. Zosia Krusberg (at right) is visiting assistant professor of physics and astronomy at Vassar College and thinks “the term ‘god particle’ is unfortunate. The Higgs boson is no more (or less) divine or spiritually significant than any other elementary particle within the standard model of particle physics.” It may be fundamental to explaining one of the most basic characteristics of the universe—namely the existence of matter and mass in addition to energy—but “it is no more (or less) important than any other physics principle underlying the Standard Model.” </p> 

<p>Last week’s discovery was monumental in that it may have finally provided experimental evidence for the Higgs Mechanism and defined the specific energy of the resulting Higgs boson, but even this “breakthrough” for particle physics leaves many scientific questions unresolved. Finding the Higgs boson completes the Standard Model, but it does not do away with many other questions and shortcomings of the current state of particle physics, such as the constituent particles of dark matter, a quantum theory of gravity, and other “mathematically subtle problems.” Not to mention that there is still significant work to be done to determine the exact nature of this newly-found particle. According to Dr. Krusberg, this particle might behave just as the Standard Model predicts or it could instead be “a Higgs-like particle that will serve as a gateway into explorations of physics beyond the Standard Model." Krusberg continued, “And I guarantee that it is this latter scenario that most of us are hoping for: physicists love nothing more than discovering the shortcomings of their theories, since this is the first step toward more fundamental theories with even more predictive power!”</p>

<p>No, finding the Higgs boson does not answer all the questions of particle physics, much less lend insight into the existence (or not) of God.  For that reason, Dr. Krusberg (like most physicists) bemoans the term ‘God particle’ and insists, “There really is nothing either literally or metaphorically god-like about the Higgs boson.”  Indeed, one writer for the British journal The Guardian reached such a point of frustration about the name that he ran a <a href="http://www.guardian.co.uk/science/blog/2009/jun/05/cern-lhc-god-particle-higgs-boson ">competition for alternatives</a>. The winner was “the champagne flute boson,” ostensibly because the bottom of a champagne bottle is an excellent and oft-used demonstration of the energy potential of the Higgs Mechanism. Or then again, perhaps it is simply because physicists thought that finally finding this shy particle would call for some of the bubbly.</p>

<p>On the other hand, some science writers and scientists can appreciate the ‘educational benefits’ of such a mysterious and controversial name because it attracts the attention of the general public and puts a relatable face on an extremely esoteric physics concept. Krusberg herself admits that “People are naturally drawn to the mysterious and the controversial, providing educators with great teaching opportunities.” But she worries about the larger social implications involved in “mixing the vernacular of physics and spirituality,” not least because such uncritical mixing can lead the non-scientific community to draw conclusions about the authority and reach of science that are not justified.</p>

<p>Understanding that the Higgs boson is not the literal stuff of God and that it does not prove or disprove God’s existence (as the name seems to suggest) extinguishes the fire under any sort of religious outcry. But this does not mean that its discovery is irrelevant to the discussion of science and faith, nor to the Christian community as a whole. As Dr. Krusberg remarks, “The recent discovery of [this] new boson at the LHC perfectly embodies the scientific process at its best (and thereby illustrates to the public why and how science works).” Scientific exploration of nature is not a fool-proof endeavor; healthy skepticism and accountability to a wide community of other researchers are absolutely critical to its success. But such evidence of the power and finesse of well-executed science as we saw last week is a testament to our ability to explore and understand the ‘how’ of the universe. God has equipped humanity with the desire, the intellectual abilities, and the collective will to recognize and explore the cosmic order and beauty of his creation. God has made our home knowable, and has given us the tools and capacities by which to know it.</p>

<p class="date"> At left, Cern researchers present their findings to a few hundred of their colleagues in Melbourne, Australia.  Image © 2012 CERN </p>

<p>It is valuable, then, for the Christian community to understand and appreciate how science works, in part to recognize that there are many instances in which science and the church work in tandem in order to better understand and better serve the world. But I think there is something else we can draw from the story of the Higgs boson, too. The nickname ‘the God particle’ has touched nerves in religious communities because it implies that science has the ability to prove or disprove divine existence by physical means.  Even though the physics community is by no means claiming insight into the divine, it is sometimes assumed by the religious community that scientists view their work as chipping away at God’s existence when they begin to understand something that was previously unknown, or known only “by faith” in esoteric theories and models.</p>

<p>And yet, regardless of motives or metaphysical interpretations, perhaps physicists' search for the Higgs boson <em> is in fact</em> an apt picture of our own search for God.  How many times have we stared up at the starry ceiling in times of crisis and prayed fervently for some kind of sign from God to assure us of his presence? And how many times has that much-desired evidence appeared only in retrospect, when we look back to see God’s hand faithfully and elegantly working in ways inscrutable at the time? It took a <em>community</em> of physicists to discern the presence of the Higgs boson. But even so, they could only do so after the fact from the cascade of particle decays it sparked; they could not observe the particle itself directly. In a similar way, though we often do not see the working of God directly, “in the moment,” we still trust in his presence and providence, often depending on friends, family and the community of the church to help us see his hand in hindsight.  </p>

<p>So while the discovery of the Higgs boson does not itself explain God, we rejoice at the subtle yet striking new insight we have into God’s creative genius via the Higgs boson and at the way God gives evidence of his faithfulness in the ordered creation itself. Perhaps, however, the greatest insight we can glean from this breakthrough is an analogy for the way God calls us to seek him and find him together, in the community of those who follow his son.</p>

        <description>Today we have a chance to witness a special moment in history as Venus transits across the disk of the Sun for people across the world to see.  Not only is this process of discovery exciting for natural science, but it has profound theological ramifications as well.</description>
        <content:encoded><![CDATA[<p>Today we have a chance to witness a special moment in history as Venus transits across the disk of the Sun for people across the world to see.  This rare astronomical occurrence may have been witnessed by Montezuma in 1520, was first predicted by Johannes Kepler in 1631, launched Captain James Cook’s expedition around the world in 1768, helped us determine the Earth's distance from the Sun in the 1882, and will not occur again until 2117. </p>

<p>The astronomy community is particularly interested in this event because <a href="http://en.wikipedia.org/wiki/Exoplanet">exoplanets</a> throughout the Milky Way galaxy regularly transit their parent stars in just the same way. This local example will allow astronomers to test and refine techniques used to determine the composition of these exoplanets' atmospheres, providing insight into whether these distant planets could possibly harbor life. </p>

<p>As Venus begins to cross in front of the disk of the Sun, Venus's atmosphere will refract the Sun's light, illuminating the backlit portion of the planet's atmosphere. Telescopes on the ground and in orbit will be trained on this thin arc of atmosphere lit up by the Sun. Astronomers will use spectrometers to break the light up into its constituent colors, from which they can determine the chemical composition of our over-heated sister planet's atmosphere. Once perfected, this same technique can be used to examine the atmospheres of planets far beyond our own solar system, offering us one of our best clues as to the habitability of these distant worlds.</p>

<p>Not only is this process of discovery exciting for natural science, but it has profound theological ramifications as well.  Surely a God capable of orchestrating both the majestic swirls of a spiral galaxy and the intricate language of DNA could bring forth life where and when He chooses, but only now are we on the verge of being able to answer the age-old question: “Did God confine His creative life-giving actions to our own planet, or does His abundant fertility extent far beyond our limited experience?” </p>

<p>In 1882, William Harkness, the Director of the U.S. Naval Observatory, was one of two astronomers to determine from the transit of Venus the distance from Earth to the Sun. Just as previous viewers could never have imagined calibrating the scale of the solar system from such an event, Harkness could not predict its importance in 2004 and 2012 (the most recent Venus transits).  As we look to the future, we can hardly imagine what new frontiers the next Venus transit of 2117 will find us exploring.</p>

<div class="see-also">"We are now on the eve of the second transit of a pair, after which there will be no other till the twenty-first century of our era has dawned upon the earth, and the June flowers are blooming in 2004. . . . What will be the state of science when the next transit season arrives God only knows. Not even our children's children will live to take part in the astronomy of that day. As for ourselves, we have to do with the present ..." ~William Harkness, the Director of the U.S. Naval Observatory, quoted in 1882 (source: NASA.gov)</div>

<p class="intro">The image above shows Venus on the eastern limb of the Sun during the 2004 transit.  As described in Tucker's essay, the faint ring around the planet comes from the scattering of light through its atmosphere, which allows some sunlight to show around the edge of the otherwise dark planetary disk. The faint glow on the disk is an effect of the TRACE telescope through which the image was captured.

        <description>The water that we take for granted was forged in the nuclear furnace of a star that exploded in the suburbs of the Milky Way galaxy billions of years ago.</description>
        <content:encoded><![CDATA[<h3>The Wonder of Water</h3>

<p>Large stars near the end of their lives regularly explode. With the force of a billion atomic bombs they strew their contents over unimaginably vast regions of space. It is, of course, a once in a lifetime event for the star—a literal “going out with a bang.” And even though recorded history is just a few thousand years long—and stars live for billions of years—we have some examples of such explosions that were noted by careful observers. </p>

<p>In A.D. 1054 what is now the Crab Nebula exploded in a flash of light bright enough to be seen in daylight for weeks. Astronomers in Korea, China, Japan, North America and the Middle East all recorded the supernova, as it is now called, although Europeans did not. It seems that Europeans, convinced that the heavens were perfect and unchanging, managed to delude themselves into not seeing this new star, which must surely have been quite visible. </p>

<p>The great Danish astronomer Tycho Brahe witnessed another supernova in 1572. Like his predecessors, he could not believe that such a dramatic change in the heavens was possible, but, apparently unlike his predecessors, he had enough confidence in his observations to know that he was seeing something remarkable. Brahe’s protégé, Johannes Kepler, witnessed another supernova in 1604, and then there were no more visible from earth until 1987, when a star exploded in a nearby galaxy known as the Large Magellanic Cloud. </p>

<p>A supernova explosion fills a massive region of space with the elements created inside the star; the powerful explosion, though, follows known laws of physics as it distributes its contents about the universe. A vast cloud of chemically enriched material, trillions of miles in diameter, results from the event—an event absolutely critical for enabling life. </p>

<p>The grand cloud that results from the supernova resembles the original cloud out of which the star formed in the first place, with one important difference—it contains a substantial roster of different materials, and not just hydrogen and helium. This time around gravity has more to work with, beginning again to gather the material in the huge cloud back into balls. The largest chunk at the center becomes another star—one that starts out with heavier elements, in addition to hydrogen. It is the ultimate recycling project, but, unlike recycling on earth, the atoms getting recycled remain in mint condition, no matter how many times they are used. </p>

<p>Some of the smaller balls end up orbiting about the second-generation star. These smaller balls contain many different atoms, and some of them have a curious molecular combination of hydrogen and oxygen. In most parts of the universe these molecules are in the form of a solid. In the others they are a gas. But on balls that are exactly the right distance from the central star, the molecules are liquid, an all-purpose, seemingly magical liquid called water. </p>

<p>Water is found in several places in our solar system. Hydrogen is, of course, the most common element in the universe, and while oxygen is far less common it is readily available to combine with hydrogen and form water. Water in the form of ice is a major component in comets and can be found in trace quantities in the atmosphere of Venus, under the surface of Mars and possibly even on some of Jupiter’s moons. </p>

<p>(We have to keep in mind, however, that more than 99 percent of the mass of the solar system is in the sun, so the distribution of elements elsewhere is almost irrelevant from the perspective of the solar system as a whole. The earth has a lot of water, but the earth is a tiny, insignificant speck compared to the sun. And because the water tends to cover so much of the surface, it is easy to overestimate the total amount. Astronomers are not sure exactly where the water on the earth came from. Constructing the early history of our solar system is an enormous challenge.) </p>

<p>From a purely scientific point of view, water is a molecule like any other—and there are lots of molecules. The laws of physics and chemistry describe its behavior, and there are no deep mysteries embedded in its familiar structure. But the laws of physics and chemistry conspire to make water unusual in ways that are critically important for life. Most peculiarly, water expands rather than contracts when it freezes. This makes ice lighter than water, so it floats. Floating ice insulates the water beneath it from the cold temperatures of winter. Absent this layer of insulation, bodies of water all over the earth would freeze solid. If ice were heavier than water, the layer of ice that formed on the top would sink to the bottom and another layer would freeze on top and sink until the entire body of water was a solid piece of ice. This would kill almost every life form in the water. </p>

<p>Water is also an effective solvent. Waste products from our bodies dissolve readily in water and can then easily be expelled. But wait—as they say on television—there is more. Water is also a remarkable coolant capable of absorbing heat and carrying it away from our bodies in the form of sweat. And water stores heat in our bodies, helping keep us warm in cold weather. Magical. </p>

<p>The creation story in Genesis records that God gathered the waters. In the King James Version that I read as a child it says, “God said, Let the waters under the heaven be gathered together unto one place, and let the dry land appear: and it was so.” In ways that the original readers of Genesis could never have imagined, the gathering of the waters was a cosmic process that took billions of years and involved all the laws of physics and chemistry. The water that we take for granted that covers so much of our planet and makes up so much of our bodies was forged in the nuclear furnace of a star that exploded in the suburbs of the Milky Way galaxy billions of years ago. </p>

<p>That water now cycles endlessly through the life process here on earth—cooling, cleansing and nurturing us. It irrigates our crops, nourishes our livestock, cleans our clothes and gets turned into snow at ski resorts. In those parts of the world where it is plentiful, clean and fresh, we take it for granted and play with it. In Quebec City they construct a hotel out of ice every winter to attract tourists and invite hardy souls to hold their weddings there, wearing parkas and snow boots. We think nothing of using thousand of gallons so our lawns will be green rather than brown in the heat of summer. Water is like air—plentiful and useful. </p>

<p>In parts of the world where fresh water is rare, its value is more apparent. There is a school in Bulawayo, Zimbabwe, where children used to walk a quarter mile during their breaks to get a drink of water. I used to walk to the hallway to get a drink when I was in school. World Vision, one of many organizations helping with water problems around the world, installed a well near the school that the children now use to get water. On school days a group of laughing, happy children can be seen working the oversized pump that takes several of them to manage. The water that emerges from its modest faucet is welcomed in ways that few North Americans can appreciate. </p>

<p>For those schoolchildren, the water is simply a welcome part of their diet and lifestyle now. Some of the children that stay in school and go on to university will eventually discover that the precious fluid—summoned from beneath the earth by a few children cranking on a lever—was created billions of years ago, deep in the heart of a star, via processes of unimaginable subtlety. Those that have learned to worship God will no doubt marvel and give thanks. </p>

<p>Water exists because the universe has a set of laws that guide its steady development from the big bang into the present. If we suppose that water and the life it enables are of no consequence, then we can dismiss these laws as irrelevant. On the other hand, if we believe that God is the creator of life and that life has a purpose, then these laws take on a new character. If God is the Creator, then these laws exist because God created them. And these laws work because God upholds them from moment to moment. Viewed by these lights, the origin of water and life are creation events, intentionally enabled by the Creator of the universe. </p><br></b>]]></content:encoded>

        <description>Baylor University Physicist Gerald Cleaver describes the changing state of our understanding of the cosmos and suggests ways that Christians can make theological sense of a theoretical Multiverse.</description>
        <content:encoded><![CDATA[<h3>Called to Christ and to Science</h3>

<p>By the time I was ten years old, I was already determined to follow a career in physics and cosmology, both because of the wonder I felt for the natural world and as a means to better resolve serious questions that were developing within me regarding the relationship between biblical interpretation and scientific discovery. The prior year I had read and studied scripture in its entirety for the first time, rather than just the piece-meal sections covered in my Sunday school classes. Whenever I look back at that year in my life, I am always glad I chose to study the New Testament before the Old Testament, rather than vice versa. From the New Testament study, I found salvation and accepted Christ into my life. But my examination of the Old Testament that followed raised serious questions for me, particularly regarding Genesis. Even as a ten-year-old, I could see the apparent conflict between Genesis and what I had already learned about the history of the universe, of earth, and of life on earth as reported by science. From science I felt amazement and wonder toward God as Creator and strongly desired to learn more about the physical laws set up by God that sustained the universe. In contrast, both of the Genesis stories of creation seemed simplistic and hollow.</p>

<p>As I continued to study, I came to believe that divine inspiration of scripture does not exempt scripture from portraying human authors’ limited (in particular, finite) understandings of the physical world.</p>

<p>Since Genesis 1 and 2 were written in a pre-scientific age, we should expect a non-scientific description of the creation process. Divine inspiration allowed the language of the time to express eternal truths regarding some aspects of God’s nature as Creator. Using stock images from the culture, the opening chapters of Genesis describe God as the ultimate Creator of all things and in charge of all things. These chapters should not be misinterpreted as scientific treatises describing the actual physics processes by which God creates all things.</p>

<p>From further study I came to understand that for almost two thousand years, many others far more knowledgeable than I had wrestled with the same issues. I was thrilled to learn that the early church fathers had developed a procedure for dealing with disagreement between scripture and scientific understanding. In 1657, the famous scientist, mathematician, and devoted Christian, Blaise Pascal, summarized the procedure of St. Augustine and Thomas Aquinas in his <em>Provincial Letters</em>:</p>

<blockquote><p>When we meet with a passage even in the Scripture, the literal meaning of which, at first sight, appears contrary to what the senses or reason are certainly persuaded of, we must not attempt to reject their testimony in this case, and yield them up to the authority of that apparent sense of the Scripture, but we must interpret the Scripture, and seek out therein another sense agreeable to that sensible truth.... And as Scripture may be interpreted in different ways, whereas the testimony of the senses is uniform, we must in these matters adopt as the true interpretation of Scripture that view which corresponds with the faithful report of the senses.</p>

<p>An opposite mode of treatment, so far from procuring respect to the Scripture, would only expose it to the contempt of infidels; because, as St. Augustine says, “when they found that we believed, on the authority of Scripture, in things which they assuredly knew to be false, they would laugh at our credulity with regard to its more recondite truths, such as the resurrection of the dead and eternal life.” “And by this means,” adds St. Thomas, “we would render our religion contemptible in their eyes, and shut up its entrance into their minds.</p></blockquote>

<p>During my teenage years, my conviction that science could be used to inform scripture and clarify our understanding and interpretation of it continued to solidify. I agreed with Galileo that, “the Bible tells us how to go to heaven, not how the heavens go.” Further, since God is the creator of all things, the physical and the spiritual, I came to understand that science as the study of the physical and theology as the study of the spiritual must be mutually consistent when both are properly understood. Inconsistency could only be the result of human misunderstanding of one or both arenas of knowledge.</p>

<p>(Some might correctly point out that science is not always as clear-cut as reason plus the report of the senses. That is, at times science also involves debates between competing interpretations, especially on the cutting edge of research. Nevertheless, ongoing scientific investigations gradually winnow away many or most proposed scientific descriptions of a given physical process, leaving only one or a few as the viable candidates. Scientific theories are formed by the general consensus of the scientific community based on overwhelming supporting physical evidence.)</p>

<p>In high school, I faced a serious medical problem, eventually identified as a brain tumor. Surgery was successful, in part due to a positive change in the tumor. In thankful response to God, I decided to pursue a career in church ministry. I determined a primary goal of my ministry would be to help the members of my future congregations develop mutually consistent and mutually supportive understandings of scripture and of science. I chose to attend Valparaiso University in Indiana, where I could, in addition to being a pre-seminary student, also double major in physics and mathematics to increase my scientific knowledge. Over the course of my four years at Valparaiso, I realized that my calling wasn’t for a church ministry, but one aspect of it would be to minister to Christians as a professional scientist, demonstrating by example that faith and science need not be at odds.</p>

<p>Thus, by way of a curved path, I did indeed follow the vocation I had initially chosen twelve years earlier. I decided once again to pursue the path that made my heart sing: studying the underlying laws and forces of the physical universe. As I was deciding which Ph.D. programs in elementary particle physics and cosmology to apply to, I became aware of a new, quickly developing subfield of particle physics called <em>string theory</em> that offered the possibility of unifying all of the known forces and matter in the universe into a single theory. I am now a successful scientist in this area, publishing discoveries that add to our understanding of particle physics and the universe.</p>

<p class="intro">In the next installment, Gerald Cleaver offers his advice to fellow Christians on how to seek after a consistent Christian worldview in which scientific and theological understandings of the universe are viewed as mutually supportive and complementary.</p>

        <content:encoded><![CDATA[<p class="intro">The six-part series that begins today is taken from a paper Dr. Keller presented at the first BioLogos Theology of Celebration Workshop in October of 2009.  It considers three main clusters of questions lay people raise with their pastors when introduced to the teaching that biological evolution and biblical orthodoxy can be compatible. As a pastor and evangelist himself, Keller takes these concerns seriously and offers suggestions for addressing them without requiring believers adopt a particular view or accept a definitive answer.  In this first installment, Keller gives an overview of the tension between biblical and scientific accounts on origins, before addressing the specific issues and responses in subsequent posts.</p>

<h3>What's the Problem?</h3>
<p>Many secular and many evangelical voices agree on one ‘truism’—that if you are an orthodox Christian with a high view of the authority of the Bible, you cannot believe in evolution in any form at all. New Atheist authors such as Richard Dawkins and creationist writers such as Ken Ham seem to have arrived at consensus on this, and so more and more in the general population are treating it as given. If you believe in God, you can’t believe in evolution. If you believe in evolution, you can’t believe in God.</p>

<p>This creates a problem for both doubters and believers. Many believers in western culture see the medical and technological advances achieved through science and are grateful for them. They have a very positive view of science. How then, can they reconcile what science seems to tell them about evolution with their traditional theological beliefs? Seekers and inquirers about Christianity can be even more perplexed. They may be drawn to many things about the Christian faith, but, they say, “I don’t see how I can believe the Bible if that means I have to reject science.”</p>

<p>However, there are many who question the premise that science and faith are irreconcilable. Many believe that a high view of the Bible does not demand belief in just one account of origins. They argue that we do not have to choose between an anti-science religion or an anti-religious science.<sup>1</sup> They think that there are a variety of ways in which God could have brought about the creation of life forms and human life using evolutionary processes, and that the picture of incompatibility between orthodox faith and evolutionary biology is greatly overdrawn.<sup>2</sup> </p>

<p>For example, there have been a number of efforts to argue that there may be evolutionary reasons for religious belief. That is, it may be that capacity for religious belief is ‘adaptive’ or is connected to other adaptive traits, passed down from our ancestors because they supported survival and reproduction. There is no consensus about this among evolutionary biologists. Nevertheless, its very proposal seems to be completely antithetical to any belief that God is objectively real. However, Christian philosopher Peter van Inwagen asks:</p>

<blockquote><p>Suppose that God exists and wants supernaturalistic belief to be a human universal, and sees (he would see this if it were true) that certain features would be useful for human beings to have— useful from an evolutionary point of view: conducive to survival and reproduction—would naturally have the consequence that supernaturalistic belief would be in due course a human universal. Why shouldn’t he allow those features to be the cause of the thing he wants?—rather as the human designer of a vehicle might use the waste heat from its engine to keep its passengers warm.<sup>3</sup></p></blockquote>

<p>Van Inwagen’s argument is sound. Even if science could prove that religious belief has a genetic component that we inherit from our ancestors, that finding is not incompatible with belief in the reality of God or even the truth of the Christian faith. There is no logical reason to preclude that God could have used evolution to predispose people to believe in God in general so that people would be able to consider true belief when they hear the gospel preached. This is just one of many places where the supposed incompatibility of orthodox faith with evolution begins to fade away under more sustained reflection.</p>

<p>However, many Christian laypeople remain confused because the voices arguing that Biblical orthodoxy and evolution are mutually exclusive are louder and more prominent than any others. What will it take to help Christian laypeople see greater coherence between what science tells us about creation and what the Bible teaches us about it?</p>

<h3>Pastors and People</h3>
<p>In my estimation what current science tells us about evolution presents four main difficulties for orthodox Protestants. The first is in the area of <em>Biblical authority</em>. To account for evolution we must see at least Genesis 1 as non-literal. The questions come along these lines: what does that mean for the idea that the Bible has final authority? If we refuse to take one part of the Bible literally, why take any parts of it literally? Aren’t we really allowing science to sit in judgment on our understanding of the Bible rather than vica versa? </p>

<p>The second difficulty is the <em>confusion of biology and philosophy</em>. Many of the strongest proponents for evolution as a biological process (such as Dawkins) also see it as a ‘Grand Theory of Everything.’ They look to natural selection to explain not only all human behavior but even to give the only answers to the great philosophical questions, such as why we exist, what life is about, and why human nature is what it is. Doesn’t belief in the one idea—that life is the product of evolution—entail the adoption of this whole ‘world -view’?</p>

<p>The third difficulty is the <em>historicity of Adam and Eve</em>. One way to reconcile what current science says about evolution is to propose that the account of Adam and Eve is symbolic, not literal, but what does this do to the New Testament teaching of Romans 5 and 1 Corinthians 15 that our sinfulness comes from our relationship with Adam? If we don’t believe in an historical fall, how did we become what the Bible says we are—sinful and condemned?</p>

<p>The fourth difficulty is <em>the problem of violence and evil</em>. One of the greatest barriers to belief in God is the problem of suffering and evil in the world. Why, people ask, did God create a world in which violence, pain, and death are endemic? The answer of traditional theology is—he didn’t. He created a good world but also gave human beings free will, and through their disobedience and ‘Fall’, death and suffering came into the world. The process of evolution, however, understands violence, predation, and death to be the very engine of how life develops. If God brings about life through evolution, how do we reconcile that with the idea of a good God? The problem of evil seems to be worse for the believer in theistic evolution.</p>

<p>I have been a pastor for almost 35 years, and during that time I’ve spoken to many laypeople who struggle with the relationship of modern science to orthodox belief. In the minds of most laypeople, it is the first three difficulties that loom largest. The fourth difficulty—the problem of suffering and death—has not been posed to me as often by parishioners. Yet in some ways the problem of suffering goes along with the third question regarding the historicity of the Fall. Without the traditional view of the historicity of the Fall, the question of evil would seem to become more acute.</p>

<p>Therefore, below I will lay out three basic problems that Christian laypeople have with the scientific account of biological evolution. Nothing here should be seen as meeting the need for rigorous, scholarly arguments in answer to these questions. These are popular-level pastoral answers and guidance. As a pastor I have had to draw heavily on the work of experts. The first question, about Biblical authority, requires that I draw on the best work of exegetes and Biblical scholars. To answer the second question, about evolution as a ‘Grand Theory of Everything,’ I need to draw on the work of philosophers. When we come to the third question regarding Adam and Eve, I must look to theologians.</p>

<p>In short, if I as a pastor want to help both believers and inquirers to relate science and faith coherently, I must read the works of scientists, exegetes, philosophers, and theologians and then interpret them for my people. Someone might counter that this is too great a burden to put on pastors, that instead they should simply refer their laypeople to the works of scholars. But if pastors are not ‘up to the job’ of distilling and understanding the writings of scholars in various disciplines, how will our laypeople do it? This is one of the things that parishioners want from their pastors. We are to be a bridge between the world of scholarship and the world of the street and the pew. I’m aware of what a burden this is. I don’t know that there has ever been a culture in which the job of the pastor has been more challenging. Nevertheless, I believe this is our calling.</p>
 
<p class="intro"><a href="/blog/creation-evolution-and-christian-laypeople-part-2">Next week</a>, Keller begins to unpack the individual questions, beginning with how we can understand evolution in relation to a literal reading of the Bible.</p>

        <content:encoded><![CDATA[<p>Developments in cosmology are often used to argue that contemporary science has eliminated the need to appeal to a creator to explain the origin and development of the universe.  Recent books by Stephen Hawking and Leonard Mlodinow [<em>The Grand Design</em> (2010)] and Lawrence Krauss [<em>A Universe From Nothing. Why There is Something Rather Than Nothing</em> (2012)] illustrate well the theme that the origin of the universe, indeed the very ancient philosophical question of why there is something rather than nothing, now falls within the explanatory grasp of cosmology and quantum physics.  Hawking and Mlodinow deny the intelligibility of a "beginning" to the universe, since time itself has emerged in the very early universe. Embracing a version of the multiverse hypothesis, they conclude: "Spontaneous creation is the reason there is something rather than nothing, why the Universe exists, why we exist.  It is not necessary to invoke God . . . to set the Universe going."<sup>1</sup> Famously, they remark that "philosophy is dead,"<sup>2</sup> and when interviewed by Larry King on CNN, Hawking opined that "theology is irrelevant."<sup>3</sup></p>

<p>For Lawrence Krauss, the sense of "nothing" employed by those who speak of creation out-of-nothing can now be adequately explained in terms of contemporary physics.  As a result, he thinks that the question, why there is something rather than nothing "is really a scientific question, not a religious or philosophical question."<sup>4</sup> No divine cause is necessary.</p>

<p>Claims by authors like Hawking and Krauss about the explanatory reach of science are ostensibly made on the basis of developments in science, but they are really metaphysical judgments, frequently advanced without a sound philosophical foundation.  If there is a metaphysical assumption lurking behind this view, it is that the mere existence of things needs no explanation.</p>

<p>Whether we speak of explanations of the Big Bang itself (such as quantum tunnelling from nothing) or of some version of a multiverse hypothesis, or of self-organizing principles in biological change (including, at times, appeals to randomness and chance as ultimate explanations), the conclusion which seems inescapable to many is that there is no need to appeal to a creator, that is, to any cause which is outside the natural order.  Nature is self-sufficient, not only with respect to the effects which it produces, but in that it somehow generates its very own existence.  Thus, the traditional notion of God's creative act disappears; it becomes a mere artefact from a less enlightened age.</p>

<p>The use of insights from cosmology to deny the need for a creator are, at times, countered by scholars who use traditional Big Bang cosmology in support of the doctrine of creation.  William Lane Craig is perhaps the most famous proponent of such a view.  But we can add the recent work of Robert Spitzer who, in <em>New Proofs for the Existence of God: Contributions of Contemporary Physics and Philosophy</em>, claims that modern physics shows us that the past time of the universe is finite.  The general argument is that an initial "singularity" [the Big Bang], outside the categories of space and time, points to a supernatural cause of the beginning of the universe.<sup>5</sup> Even Pope Pius XII once remarked (in 1951) that this cosmology offered support for what the opening of Genesis revealed.  If the universe has such a beginning, it must be created.<sup>6</sup></p>

<p>Thus, we have some cosmologists who deny the intelligibility of the very notion of a beginning and others who argue for variations of an eternal universe.  Since there is no real beginning to the universe, there is no need to speak of a creator.  On the other hand, we have others who say that science affirms an absolute beginning to the universe, which serves as a warrant for the doctrine of creation. Despite fundamental differences as to what contemporary cosmology tells us (beginning or no beginning), all these views tend to identify what it means for the universe to be created with its having a temporal beginning.  This emphasis on beginnings leads to confusion about creation.</p>

<p><img src="http://biologos.org/uploads/static-content/St-thomas-aquinas.jpg" alt="" height="396" width="260"  style="margin: 0pt 0pt 20px 20px; float: right;"/>In order to disentangle much of the confusion evident in contemporary discussions about creation and cosmology, it is useful to reprise the clear distinctions Thomas Aquinas (1224-1274) draws between creation and the natural sciences.  For Thomas, creation is a topic for metaphysics and theology.  The doctrine of creation affirms that all that is, in whatever way or ways it is, depends upon God as cause.  The natural sciences have as their subject the world of changing things: from subatomic particles to acorns to galaxies.  Whenever there is a change there must be something that changes.  Whether these changes are biological or cosmological, without beginning or end, or temporally finite, they remain processes.  Creation, on the other hand, is the radical causing of the whole existence of whatever exists.  Creation is not a change. To cause completely something to exist is not to produce a change in something, is not to work on or with some existing material. When God's creative act is said to be "out of nothing," what is meant is that God does not use anything in creating all that is: it does not mean that there is a change from "nothing" to "something."</p>

<p>Cosmology and all the other natural sciences offer accounts of change; they do not address the metaphysical and theological questions of creation; they do not speak to why there is something rather than nothing.  It is a mistake to use arguments in the natural sciences to deny creation.  Similarly, it is a mistake to use arguments in cosmology to seek to confirm the doctrine of creation.</p>

<p>Thomas does think that reason alone can lead us to a recognition that all that is is caused by God, but the path to such a conclusion is in metaphysics, not in the natural sciences.  Arguments for God as Creator are different from arguments in natural philosophy for God as the source of order and intelligibility in the universe.  Explanations of order and design in nature are different from accounts of why there is something rather than nothing.</p>

<p>Creation is not primarily some distant event; rather, it is the on-going complete causing of the existence of all that is. At this very moment, were God not causing all that is to exist, there would be nothing at all.  Creation concerns first of all the origin (source of being) of the universe, not its temporal beginning.  Thomas thought that, in principle, reason alone cannot conclude definitively as to whether or not the universe had a beginning. He did believe, as a matter of faith (confirmed by the decree of the Fourth Lateran Council in 1215), that the universe had a temporal beginning, but for him there is no contradiction in the notion of an eternal, created universe: for were the universe to be without a beginning it still would have an origin, it still would be created, it still would depend upon God for its very existence. Whether the universe is eternal or temporally finite concerns the kind of universe God creates. The fundamental sense of what it means for the world to depend upon God as its cause ought to be distinguished from whether or not what God causes has a beginning.  Otherwise, we might be led into the error of thinking that to deny a beginning is to deny that dependence upon God.</p>

<p>It was the genius of Thomas Aquinas to distinguish between creation understood philosophically, with no reference to temporality, and creation understood theologically, which included, among other things, the recognition that the universe does have an absolute temporal beginning.</p>

<p>God’s creative power is exercised throughout the entire course of cosmic history, in whatever ways that history has unfolded.  God creates a universe in which things have their own causal agency, their own true self-sufficiency—a nature that is susceptible to scientific analysis.  No explanation of cosmological processes, nor biological change for that matter, regardless of how radically random or contingent such an explanation claims to be, challenges the metaphysical account of creation, that is, of the dependence of the existence of all things upon God as cause.</p>

<p>In today’s video, Michael Ramsden discusses the importance and meaning of <em>mystery</em> in the Bible. It does not come from ignorance, as the word is often used in modern times, but rather it is mystery born out of insight and wonder, one that is informed by understanding the world around us. As Ramsden notes, Jesus’ use of children to describe the nature of faith isn’t meant to emphasize their ignorance, but rather their sense of trust for those who love them. Likewise, we should not be afraid to search out answers, as if knowledge will lessen our faith in God. Rather we should trust that our explorations will only strengthen our understanding in Him.</p>

        <description>“Nature is messy,” a geologist tells writer John McPhee, “Don’t expect it to be uniform or consistent.” McPhee’s books on geology tend to emphasize the humbling effect of the real earth on the overly&#45;intellectual geologists who want to over&#45;simplify it.</description>
        <content:encoded><![CDATA[<p class="intro">In part five, Kennedy explored the "provability" of Darwin's theory and looked at two types of thinkers: <em>Totalizers</em> and <em>Tentative Investigators</em>. Socrates and Plato, he said, were "Totatlizers"; Aristotle was a "Tentative Investigator." Today Kennedy expresses his respect for Aristotle's approach as he reflects on the messiness of the natural world and the inability of scientific models to fully reflect it.</p>

<h3>Aristotle’s Pocketknife</h3>

<p>Aristotle is most often presented in textbooks as a systematic thinker; however, if you read his books, you will realize that he was a <em>Tentative Investigator</em>, a tinkerer.  Even his books on methods of logical thinking come together as a sort of Swiss Army knife approach to being an intellectual.  Back when I was a college student, I read two books that impressed me with the importance of Aristotle: <em>Zen and the Art of Motorcycle Maintenance</em> (1974), a travel-thinking book, and <em>Saint Thomas Aquinas: “The Dumb Ox”</em> (1933) by G. K. Chesterton. The tinkering, earthy, humanistic Aristotle is a theme in both. Over the decades since then I have increasingly found wisdom in Aristotle’s methods.  G. K. Chesterton wrote that Aristotelian thinking “might be a humbler or homelier thing than the Platonic mind; that is why it was Christian.”  He noted that when following in the steps of Aristotle one walked a “lower road,” one humbled in the manner of God “when he worked in the workshop of Joseph.”</p>

<p>For Aristotle natural history and ancient history required different fold-out tools from his pocketknife.  Natural history depended upon observation and use of various types of categorizing and generalization.  Natural history could be done by oneself alone. Ancient history, on the other hand, required a courtroom approach, the evidence, analysis, and judgment all being aspects of a social art.  Human history was political for Aristotle.</p>

<h3>Orienteering</h3>
	
<p>The four of us, sweating as we hiked upward through switchbacks, decided to take a rest. On a big rock, I laid out the map, compass, and altimeter/barometer and pointed to Mount Darwin in the distance. Dave looked at the map and compass and corrected me.</p>

<p>“No. That rise in the ridge next to it is Darwin.”</p>

<p>I, being his former professor, corrected his error. I checked the map’s compass variation and adjusted it again to magnetic north. I showed him, based on our elevation, where we were on the trail. If we were there on the map, then the real Darwin was at this angle from us.</p>

<p>Dave, a veteran of the first Gulf War whose Navy job was in the high-tech bowels of the aircraft carrier <em>Constellation</em>, was not impressed. “No. That one is Darwin.”</p>

<p>“No,” I replied. “Look at the way that rock points up. That is the pinnacle of Darwin.”</p>

<p>“No. A little to the left is Darwin.”</p>

<p>He wouldn’t back down. This was mountain orienteering. I think I should have some authority here. As for Dave, yes, he had lots of training and experience with maps and instruments; however, it was my compass! We agreed to disagree. I gathered the tools of my leadership, and humped my pack onto my back.</p>

<h3>Nature is Messy</h3>

<p>“Nature is messy,” a geologist tells writer John McPhee, “Don’t expect it to be uniform or consistent.” McPhee’s books on geology tend to emphasize the humbling effect of the real earth on the overly-intellectual geologists who want to over-simplify it. In <em>Rising from the Plains</em> (1986), McPhee rambles through Wyoming with an aging U.S. Geological Survey geologist who heaps disdain on “Megathinkers” who don’t get dirty working in the field. Field geologists have to be more humble and face every day the quirky and irregular aspects of places like Wyoming. The government, however, is downsizing the regional offices. “The name of the game now is ‘modelling,’ on office computers at the national office.” He describes modelers as working in a “black box” where the earth becomes an abstraction and the awkward individual facts evident in the field get smoothed over.</p>

<p>Maps are models. Every map or globe is an abstraction making trade-offs with reality.  Modeling was one of the tools of natural science in the Aristotelian pocketknife. Generalizations that smooth over the particularities can be very useful.  Maps are generalizations.  Maps are abstractions.  Reality is so messy that it is oftentimes more useful to not look too closely.  Step back from the messiness and a person can often find abstractions more useful than reality.</p>

<p></p>

<p>Hiking up the switchbacks leading to Mount Darwin we shared the trail with several people that I noted were carrying GPS units.  At the technology counter at backpacking stores I have heard people fall into raptures of amazement that the little screen shows their position exactly on the earth.  Trouble is: a GPS unit actually calculates its position by triangulation with satellites, and then correlates that position to a map in its memory—not to the actual earth.</p>

<p>To get really picky, the GPS unit does not work directly with the actual shape of the earth. The actual earth is slightly flattened. GPS uses an ideal sphere as a model upon which it imposes circular latitude and longitude lines. When a handheld GPS calculates its position by latitude and longitude—which is its best work—it is not calculating its place actually on earth. It is calculating its place on a sphere that is a close representation of a non-spherical earth. This is one of the reasons a GPS will always be slightly imprecise. As with most things, the further we dig, the more squishy our knowledge.</p>

<p>The earth is elastic in erratic ways. Not only is the earth’s shape and distribution of its mass not stable, the earth also wobbles, causing the north and south poles to wobble. The poles don’t wander too far, but with poles whose positions aren’t stable.  We can’t know our precise latitude on maps because latitude is an angle measured from wobbling north and south poles. The problem affects astronomers and such things as the target systems inside intercontinental ballistic missiles. Today there is an International Terrestrial Reference Frame that uses computer models to quantitatively estimate polar motion and its effects. It is very accurate; however, we still can only estimate the future latitude of a point on earth and any statement of position is accurate only within a range of unknowing.</p>

<p></p>

<p>Magnetic north is also problematic. When hiking in the back country, the first thing to do with a map is to use a compass and the information about magnetic variation on the map to orient magnetic north to true north. Good maps tell you the average magnetic variation for a general region for the publication year of that map. Extremely good maps such as nautical charts from the National Oceanographic and Atmospheric Administration (NOAA) tell you the yearly rate of variation change and have lots of information about areas of magnetic disturbance where your compass will not work. All these maps go bad after a few years. There is a short window of accuracy to maps and their magnetic predictions. Magnetic north wanders erratically. Every day it wanders over a region of about 85 km. Year to year, it heads in a generally northwest direction. Also, the intensity of its force is diminishing. There is a possibility that it might flip-flop soon, as it has done erratically in the past, thus causing all compass needles to go through a period of pointing nowhere and eventually pointing south instead of north.</p>

<p>A GPS is not dangerous to use. It is only dangerous to be overconfident about what it tells you. For Dave and me, with our maps and compass laid out on a rock, the weaknesses of our information are not a problem. Navigating in the High Sierra is pretty simple. The deep assumptions and problems submerged in my map won’t affect us. On the other hand, knowledge of its deep assumptions and instabilities can encourage a little humility and care along the way.</p>

<p>Much that goes on in universities is like what goes on inside a GPS unit. We find it useful to create models, and then study the models as reality. However, all members of universities should strive to be wise about keeping the “useful” separate from the “true.” At universities, we are supposed to try and hold to them both. We get into trouble when we assume that they are identical or only care about one or the other.</p>

<h3>Mount Mendel</h3>

<p>After trekking up a bunch of switchbacks, we reached Blue Lake at 10,400 feet. We were through the steepest part of our day’s hike and were seeing an increasing amount of snow and ice. I kept an eye on the barometer, looking for trends that would show a change in the weather. We had a high-pressure air mass over us the whole weekend, keeping bad weather away and blue skies above, but I watched barometric pressure anyway as we were going up. We were climbing late in the season, and big mountains can create their own weather. If the barometric pressure started dropping faster than it should with the higher altitude, we would be looking at rain or snow. Though Blue Lake was pleasantly surrounded by trees, we were headed up above tree-line where we could see only chunks of rock.</p>

<p></p>

<p>Up close, the High Sierra ridges are not pretty.  The High Sierra is being violently pushed up as California, geologically, keeps jamming itself into Nevada.  Approaching from the west, it is easier to see that Mount Darwin and Mount Mendel are really just two high spots on a long sharp ridge.  Approaching from the east, we won’t see Mount Mendel (13,710΄) until we are on the ridge leading to Darwin’s summit. </p>

<p>Theodore Solomons, when naming the Evolution Group in 1895, did not name Mount Mendel. At that time, Gregor Mendel (1822–1884) was unknown to all but a tiny few scientists. He is considered the father of genetics, the field that, more than any other, has partnered up with Darwinism in mutual confirmation and explanation. The peak’s name was proposed by the Sierra Club in 1942. The peak had not been named earlier because many thought the peak was already named after Alfred Russell Wallace. But Wallace had another peak. Even the 1912 and 1918 USGS maps misnamed the peak. So when the confusion was worked out, there was an unnamed summit next to Mount Darwin. With genetics growing and elementary textbooks praising Mendel as a model scientist his was the perfect name for the mountain.</p>

<p>Beginning around 1900 scientists began to realize that Mendel offered a <em>controlled</em>, <em>experimental</em> method to get at what Darwin only observed in the wild. Mendel found a multi-generational, mathematically understandable pattern in peas that enhanced the conviction that there was a physical mechanism in living things acting as a shuffler of traits. Mendel’s experiments did not prove <em>randomness</em>, but they did show that a variation and selection process was happening with mathematical consistency.  Mendel’s work showed that it might be possible to use his patterns of hybrid peas to make models of evolution, especially models that, sidestepping any messiness, could reach deep beyond ancient history back into the natural history of human beings.</p>

<p></p>

<p>Dave and I wanted to get over to the top of Mount Mendel when we reached the top of Darwin, but it seemed unlikely that we would have time on this trip. Standing on the summit of both Mount Darwin <em>and</em> Mount Mendel would be a thrill, but we did not have unlimited time and Steven was walking slower than I expected.</p>]]></content:encoded>
