There was nothing before the Big Bang; says Stephen Hawking

British physicist Stephen Hawking has said that there was nothing around before the big bang that created our universe.

Neil deGrasse Tyson, another famous physicist, asked Hawking to express his opinion about what the universe looked like before the Big Bang, during the show on National Geographic called Star Talk.

According to this theory, the history of the universe is not a flat line but a four-dimensional, curved object, "like the surface of the Earth, but with two more dimensions", Hawking said.

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.

Think your friends would be interested? But, he said that that didn't there before Big Bang event, it began after the Big Bang when the Universe started expanding. Some of the most strident opposition to this theory comes not from other scientists but from theologists and lay-believers who pose the question (not necessarily in as many words): "If there was something that exploded during the Big Bang, where did that something come from?"

Hawking went on to basically explain that before the Big Bang, time didn't exist.

"Conventional real time is replaced by imaginary time".

Air India said on Tuesday that while it had issued such a request, the regulator had yet to give it a positive answer. Air India had earlier announced to start direct flight between Delhi and Tel Aviv.

"The boundary condition of the Universe ... is that it has no boundaries", said Hawking.

"There is nothing south of the South Pole, so there was nothing around before the big bang". For instance, he explained how the South Pole obeys the normal laws of physics but indeed there is nothing in South of the South Pole.

The Big Bang theory holds that the universe in retrospective can shrink to the size of an extremely small "subatomic ball" known as the singularity.

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

During one of his lectures, Hawking had stated that there are no observable consequences from what occurred before the Big Bang.

It's not an easy concept to take on, but you just have to have faith that space and time didn't exist as we know it on Earth before the Big Bang. Instead, time and space extend from this singular point in time, like the degrees of latitude on the planet Earth. "Even the amount of matter in the universe, can be different to what it was before the Big Bang, as the Law of Conservation of Matter, will break down at the Big Bang".
