An earlier universe existed before the Big Bang and can still be observed today, Sir Roger Penrose has said, as he received the Nobel Prize for Physics.

“The Big Bang was not the beginning. There was something before the Big Bang and that something is what we will have in our future.

“We have a universe that expands and expands, and all mass decays away, and in this crazy theory of mine, that remote future becomes the Big Bang of another aeon.

“So our Big Bang began with something which was the remote future of a previous aeon and there would have been similar black holes evaporating away, via Hawking evaporation, and they would produce these points in the sky, that I call Hawking Points.

“We are seeing them. These points are about eight times the diameter of the Moon and are slightly warmed up regions. There is pretty good evidence for at least six of these points.”
