Stephen Hawking is considered one of the theoretical physicists in history. But, how much does he know? Can he explain what existed before time?
In a recent conversation with astrophysicist Neil deGrasse Tyson (via Popular Science), the famed physicist offered his take on what there was before the moment that time started: The Big Bang. He said there was nothing.
“Nothing was around before the big, big bang,” Hawking said. “According to Einstein’s General Theory of Relativity, space and time together form a space-time continuum or manifold which is not flat but curved by the matter and energy in it.”
He also says that before the Big Bang, time didn’t exist either.
