Stephen Hawking has revealed that he won a bet against Neil Turok over his Big Bang Theory.
The renowned physicist told BBC Radio 4's Today programme that he had a bet with the South African physicist, which he won as the discovery of gravitational waves in the universe proved his theory of 'inflation', the Mirror reported.
Inflation is the huge burst of energy after the big bang, when the universe inflated in size by 100trillion times, faster than the speed of light, and proves that Turok is wrong in believing there were a series of big bangs.
