Stephen Hawking explained situation before Big Bang

  • The boundary condition of the universe... is that it has no boundary Hawking told physicist Neil de Grasse Tyson

Everyone knows about the Big Bang Theory, right? But, some scientists and theologists questioned that what was there before the Big Bang.

"Ordinary real time is replaced by imaginary time, which behaves like a fourth direction of space". Like Euclid, Hawking believes imaginary time is a "four-dimensional curved surface like the surface of the Earth, but with two more dimensions".

In a new episode of Star Talk, the famous British physicist Stephen Hawking spoke with host Neil deGrasse Tyson to talk about what existed before Big Bang, this conceptual line only "visible" by calculation, which is impossible to cross.

He went on: "Jim Hartle and I proposed a "no-boundary condition". I guess time has passed a certain pace, only to discover that this is only my idea", says Hawking. In other words, the Euclidean space-time continuum is an endless closed surface, much like the surface of the Earth. Taking the example of Earth, he said: "One can regard imaginary and real-time beginning at the South Pole".

Just like there is nothing beyond the South Pole, there is also nothing beyond the Big Bang, Hawking explained.

Einstein's General Theory of Relativity attempts to justify how humans perceive the force of gravity that comes from the curvature of time and space.

The Big Bang Theory is one of the most popular and most logical explanations of how the universe started to exist.

Hawking stated that time was likely in a bent state, located in the nearly infinitely small quantum foam of the singularity before the big event occurred, noting that time was distorted, approaching closer to nothingness, but never becoming nothing.

'At a singularity, all the laws of physics would have broken down.

To answer what happened before the Big Bang, Hawking took a so-called Euclidian approach to quantum gravity to describe the beginning of the universe.

The Big Bang is the moment when something tiny started to grow over the next unlimited years and then it became what we know now as the universe. According to the theory, the universe began with a small singularity which occurred over 13.8 billion years ago into the universe that is known at present.
