Stephen Hawking Reveals What Existed Before the Big Bang

In an interview with astrophysicist Neil deGrasse Tyson, iconic physicist Stephen Hawking recently revealed what he believes existed prior to the Big Bang.

 “Nothing was around,” said Hawking, who fortunately elaborated on this point. “The Euclidean space-time is a closed surface without end, like the surface of the Earth,” said Hawking, referring to the four-dimensional conceptual model that incorporates the three dimensions of space with time. “One can regard imaginary and real time as beginning at the South Pole, which is a smooth point of space-time where the normal laws of physics hold. There is nothing south of the South Pole so there was nothing around before the Big Bang.” At least, there was nothing around that humans can currently experience or conceptualize.

Hawking has offered some pessimistic assessments of the near-future of our planet. He predicts that the Earth will become a ball of fire within the next 600 years while also warning humanity that we have less than a century to leave Earth before it becomes uninhabitable. He also warned about the existential dangers of artificial intelligence. “Computers can, in theory, emulate human intelligence, and exceed it,” he said in 2017. “Success in creating effective AI, could be the biggest event in the history of our civilization. Or the worst. We just don’t know. So we cannot know if we will be infinitely helped by AI, or ignored by it and side-lined, or conceivably destroyed by it.”
