There was nothing around before the Big Bang, according to renowned British physicist Stephen Hawking.
Speaking during a TV talk show Star Talk, aired on Sunday on National Geographic Channel, Hawking propounded his theory on what happened before the universe came into existence.
Hawking’s theory lies upon the assumption that the universe has no boundaries, the Xinhua reported late on Sunday.
“Nothing was around,” Hawking told astrophysicist Neil deGrasse Tyson on his show StarTalk.
“According to Einstein’s General Theory of Relativity, space and time together form a space-time continuum which is not flat, but curved by the matter and energy in it,” Hawking explains. “In the Euclidean approach, the history of the universe in imaginary time is a four-dimensional curved surface like the surface of the Earth, but with two more dimensions.”
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.
