When we refer to the vastness of the cosmos, exactly how large of a space are we describing? The picture above shows the galaxy NGC 4214, located about 13 million light years from Earth. Currently, the farthest observed galaxy is A1689-zD1, located almost 13 billion light years from Earth. How much further does our universe extend past this distant galaxy?
In an interview for Closer to Truth with Robert Lawrence Kuhn, astrophysicist Andre Lindei discusses exactly what our infinite universe looks like. Lindei, one of the authors of "inflationary cosmology", presents a model of our universe consisting of countless collections of enormously large "balloons."
Thus, the 1028 centimeters we can see with our most powerful telescopes is but the smallest sliver of this infinite collection of spaces. As Lindei says, "We are seeing nothing yet," because our universe is only 14 billion years young.
