The Big Bang Theory has moved on a bit. This is the latest in Cosmic Origins. Here is a quote by Alan Guth Professor of Physics at the Massachusetts Institute of Technology (MIT). And author of The Inflationary Universe. If the inflationary theory of cosmology is right, it means that the universe is far larger than we had thought. Most likely the universe is also much older than we thought, and it includes not just one, but an infinity of big bangs. To read a little more on multiple big bangs and why our currently observable universe is most likely just merely a speck in an infinite universe, follow this link - Infinite Bubble Universes Cris
