All of the matter and energy in the entire universe was once contained in "a space so small that it would make a proton look enormous." (Bill Bryson, A Short History of Nearly Everything) This, according to many scientists, was the situation before the Big Bang. Some experts think there may have been untold numbers of universes before this one, constantly expanding and then contracting back to that tiny point of matter. That we exist in this one is, they say, simply a matter of chance. "Although the creation of a universe might be very unlikely, Tryon (of Columbia University) emphasized that no one had counted the failed attempts." What were the other universes like, I wonder?
