Sir Roger Penrose, known for his work proving that black holes exist has proposed the theory that there was a universe before our own. He points towards six ´hot´ points, also known as Hawking Points, in the sky that are multiple times the diameter of the Moon.
Sir Penrose states that these Hawking Points are ´dead´ black holes, from a previous universe. Prof. Hawking theorized that the evaporation of black holes is possible due to radiation leaks. The time needed for such evaporation to occur is enormous, and more than likely longer than our universe has existed. This leads sir Penrose to state that if these Hawking Points are indeed ´dead´ black holes, and Prof. Hawking’s theory is correct, they are observable proof of previous black holes.
Sir Roger said: “I claim that there is observation of Hawking radiation.¨
“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 eon.¨
“So our Big Bang began with something which was the remote future of a previous eon 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.”
The theory is not without controversy. However, it has been long speculated amongst some scientists that there is a cycle of birth, death, and rebirth of the universe. These observations help substantiate this idea further. Scientists deem it likely that the Universe expands after a Big Bang and after time contracts again in a ´Big Crunch´ and so on.
