The world-famous physicist, who died last Wednesday aged 76, was a co-author to a mathematical paper in which he sought to prove the so-called “multiverse” theory, according to a report by U.K. newspaper The Sunday Times. This theory imagines the existence of many separate universes other than our own.
The research, submitted two weeks ago, sets out the maths needed for a space probe to find experimental evidence for the existence of a “multiverse”. This is the idea that our cosmos is only one of many universes. If such evidence had been found while he was alive, it might have put Hawking in line for the Nobel prize he had desired for so long.
Hawking’s final work — titled “A Smooth Exit From Eternal Inflation” — is being reviewed by a leading scientific journal. In it, he predicted how our universe would eventually fade to darkness as the stars run out of energy.
Hawking, had previously warned that Earth would turn into a giant ball of fire by 2600. Therefore, humans would eventually need to colonize another planet or face extinction, he said.
Hawking claimed at the 2017 Tencent WE Summit in Beijing that “humans will turn the planet into a giant ball of fire by the year 2600”
Overcrowding and energy consumption will render Earth uninhabitable in just a few centuries, Hawking said via video:
Shades of John Ehrlich. Perhaps the proverbial “grain of salt” is in order on Hawking’s Earth prediction.
