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. 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.
