Before the Big Bang

Legendary physicist Sir Roger Penrose says he has found the first evidence of an eternal, cyclic cosmos that is refreshed by Big Bangs, of which there have been many.

The current cosmological census is that the universe began 13.7 billion years ago with the Big Bang. … The Big Bang model holds that everything that now comprises the universe was once concentrated in a single point of near-infinite density. Before this singularity exploded and the universe began, there was absolutely nothing. … Sir Roger Penrose, one of the most renowned physicists of the last fifty years, takes issue with this view. He points out that the universe was apparently born in a very low state of entropy, meaning a very high degree of order initially existed, and this is what made the complex matter we see all around us possible in the first place.
