Professor Stephen Hawking Says he Knows what Happened Before the Big Bang

Professor Stephen Hawking Says he Knows what Happened Before the Big Bang

It's one of the biggest brainteasers out there: If the Big Bang made all that we think about, what the heck was around before the big bang?

This means that anything that preceded it can not be applied to our understanding of time and existence. For him, the imaginary time works like a fourth direction of Space.

Astrophysicist Hugh Ross of the Christian apologetics group Reasons to Believe has taken issue with the claim of notable British theoretical physicist Stephen Hawking that nothing existed before the Big Bang.

According to his theory, the universe was shrunk and condensed to an incredibly dense ball of heat and energy the size of a single atom. Just as it is possible to travel all around the Earth's surface without encountering any edge, the Big Bang would not be the beginning of space-time anymore than on Earth the North Pole would represent the beginning of the surface of the earth.

Again, that's a tough concept to wrap your head around and physicists say our understanding of the universe and the Big Bang is an evolving concept - so there could be more to learn in time to come. "It just seemed that way from mankind's perspective", Hawking said, hinting that a lot of what we believe is derived from a human-centric perspective, which might limit the scope of human knowledge of the world.

If you then add a vertical line, this is what Hawking calls imaginary time, and is what was around before the Big Bang. Since there is no concrete evidence about what was around "nothing" where nothing is actually something that was there before the Big Bang. He says the boundary condition of the universe is that it has no boundary. "There was nothing around the Big explosion", he said. Therefore it is better to describe the Euclidean approach. But, he said that that didn't there before Big Bang event, it began after the Big Bang when the Universe started expanding.

"In the Euclidian 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". Instead, time and space extend from this singular point in time, like the degrees of latitude on the planet Earth.

If we were to move back in time from the Big Bang, the "arrow" of time shrinks infinitely as the universe becomes smaller, never reaching a clear starting point.

"It was always reaching closer to nothing but didn't become anything", he said.
