Stephen Hawking recently said he knows what happened before the Big Bang. Other times, he blew our minds.
Famed physicist Stephen Hawking definitively answered one of humankind's grandest questions last week — What was around before the Big Bang? "Nothing was around," Hawking told astrophysicist Neil deGrasse Tyson March 10 on his show StarTalk.
Saying he uses a "Euclidean approach to quantum gravity to describe the beginning of the universe," Hawking goes deep into what that actually means. A degree in astrophysics will help you understand, but he makes a concise point about the Big Bang, which happened nearly 14 billion years ago.
"The Euclidean space-time is a closed surface without end, like the surface of the Earth," he said. "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."
Hawking would regularly blow our minds with his theories on what happened and what's to come in our universe. Last year, he explained how we humans may have about 100 years left on Earth. Then there was his prediction Earth would become a "ball of fire" within about 600 years.
