Sir Roger, 89, who won the honour for his seminal work proving that black holes exist, said he had found six ‘warm’ points in the sky (dubbed ‘Hawking Points’) which are around eight times the diameter of the Moon.
They are named after Prof Stephen Hawking, who theorised that black holes ‘leak’ radiation and eventually evaporate away entirely.
The timescale for the complete evaporation of a black hole is huge, possibly longer than the age of our current universe, making them impossible to detect.
However, Sir Roger believes that ‘dead’ black holes from earlier universes or ‘aeons’ are observable now. If true, it would prove Hawking’s theories were correct.
Sir Roger shared the World Prize in physics with Prof Hawking in 1988 for their work on black holes.
Speaking from his home in Oxford, 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 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.”

Sir Roger has recently published his theory of ‘Hawking Points’ in Monthly Notices of the Royal Astronomical Society.
