The Big Cycle

The universe supposedly started with the Big Bang, but that begs the questions-- what was before the Bang, and what caused the Bang?  Some physicists argue those questions have no meaning, but others, including Einstein, have proposed variations on the cyclic universe theory-- that the universe expands and contracts, crunches and bangs, in a cycle that goes on forever.

Science, in fact, has no idea as yet how the universe began.
