Here are the last two paragraph’s of Stephen Barr’s article “Anthropic Coincidences,” from First Things (about 2001):
“The traditional answer is a good one, but there may be another. It turns out that the very age and vastness of the universe may have an “anthropic” significance. Life emerged in our universe in a way that required great stretches of time. As we have seen, most of the elements needed for life were made deep in stars. Those stars had to explode to disperse those elements and make them available before life could even begin to evolve. That whole process alone required billions of years. The evolution of human life from those elements required billions of years more. Thus, the briefness of human life* spans and even of human history compared with the age of the universe may simply be a matter of physical necessity, given the developmental way that God seems to prefer to work. It takes longer for a tree to grow to maturity than the fruit of the tree lasts. It took much longer for the universe to grow to maturity than we last.
Physics can also suggest why the universe has to be so large. The laws of gravity discovered by Einstein relate the size of the universe directly to its age. The fact that the universe is many billions of light-years across is related to the fact that it has lasted several billions of years. Perhaps we would be less daunted by a cozy little universe the size, say, of a continent. But such a universe would have lasted only a few milliseconds. Even a universe the size of the solar system would have lasted only a few hours. A universe constructed in such a way as to evolve life may well have had to extend widely in space as well as in time. It may well be that the frightening expanses that are so often said to be a sign of human insignificance may actually, like so many other features of our strange universe, point to man, as they also proclaim the glory of God.”
