Nothing was around before the origin of the universe: Stephen Hawking

While all scientists have been examining different things to find out the answer, Stephen Hawking has given a simple and direct answer to this question.

What exactly was there before the massive Big Bang took place? In Hawking's own words, "it is not the kind of time we normally experience" and the four-dimensional "Euclidean space-time" it would create with the three dimensions of space would be nearly impossible for anyone to imagine.

According to Hawking's theories, this means that the universe literally did not exist before the Big Bang.

"In order terms, the Euclidian space-time is a closed surface without end, like the surface of the Earth". For him, the imaginary time works like a fourth direction of Space.

To visualise this, imagine a horizontal line with past running to the left and future to the right.

Physicist Neil deGrasse Tyson, on his "Star Talk" show, engaged his fellow physicist Stephen Hawking down in a conversation to ask his view about The Big Bang and what came before it.

Hawking's theory lies upon the assumption that the universe has no boundaries, the Xinhua reported late on Sunday.

Inside this speck, the laws of physics and time as we know them cease to function, and time as we understand it did not exist.

Hawking further furnishes his theory on time before the Big Bang that it was present but in a bent state at the infinitely small quantum foam of singularity before Big Bang came into existence. One of the famous theory of is the Big Bang theory.

Others say our universe is simply just one of an infinite number of universes suspended in some higher dimension.

Hawking had stated in his previous lectures that the universe was the result of Big Bang.

"Conventional real time is replaced by imaginary time". Since there is no concrete evidence about what was around "nothing" where nothing is actually something that was there before the Big Bang.

According to Mr. Hawking, "the boundary condition of the universe is that it has no boundary".

"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".

The Euclidean approach dates back to Ancient Greece as a mathematical system that consists of a set of starting logical proposals or starting points to determine and deduct new proposals with logic as their base.

"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 was nothing around the Big explosion", he said.
