Brian Cox, a British physicist and University of Manchester professor explained what happened before the Big Bang.

He investigated the crucial question of our existence, aiming to discover how the universe came to be. He discussed how discoveries of other galaxies have helped us comprehend how we came to be, as well as the technologies utilized along the route, as he looked at the different cutting-edge space missions that have gotten us closer to the answer.

As the documentary begain, he said: “Our universe is an enigma, an endless inexhaustible paradox.

“There are trillions of planets and one of them nurtured beings capable of contemplating this cosmic drama, miraculously improbable, brief candles flickering against the eternal night.”

For thousands of years, humanity has been wondering where it all began.

Religion has provided the answer for the majority of history.

However, when science progressed and the secular world expanded, disciplines such as physics moved in to fill the hole.

Ironically, the dominant cosmological model describing the existence of the observable world from the beginning of time to the present was proposed in the 1920s by a Belgian priest named Georges Lemaître.

He believed that the cosmos originated with a single primordial atom.

Scientists have built on this throughout the years, and it is largely acknowledged to be the event that led to our origins.

But, according to Prof. Cox, there was a time before the Big Bang when the universe did exist.

He explained: “We know that 13.8 billion years ago, this space that I’m standing in now, and the space you’re standing in now, and all the space out to the edge of the observable universe, containing two trillion galaxies, was very hot and veer dense and has been expanding ever since.

“Now, that implies that way back, everything was closer together.

“Everything was contained in a very small speck.

“But, how small was that speck? And how did it come to be?

“We used to think that the universe emerged in that state, very hot and very dense, at the beginning of time.

“And we used to call that the Big Bang.

“But now, we strongly suspect that the universe existed before that.

“And in that sense, it’s possible to speak of a time before the Big Bang.”

There was no matter before the Big Bang, and all that existed was space-time and an ocean of energy that was practically calm, but softly vibrating.

Prof Cox says we should “picture it as a near-still ocean of energy, filling the void”.

While there were no structures in this location, the energy had an effect on space, causing it to extend.

This would not have resulted in the gradual spread that we observe today, “but an unimaginably violent expansion”.

Inflation is the term used to describe this expansion.

Sir Roger Penrose made a similar case when he got the Nobel Prize in Physics last year.

After receiving the award for his seminal work proving the existence of black holes, he announced that he had discovered six “warm” points in the sky, which he dubbed “Hawking Points” after the late physicist Stephen Hawking, who proposed that black holes ‘leak’ radiation and eventually evaporate away completely.

These points were almost eight times the size of the Moon.

The timescale for a black hole’s entire evaporation is enormous — maybe longer than the duration of our present universe, making them hard to detect.

Sir Roger, on the other hand, believes that “dead” black holes from prior universes or “aeons” can now be observed.

If true, it would validate Prof. Hawking’s theories.

Sir Roger said: “I claim that there is observation of Hawking radiation.

“The Big Bang was not the beginning.

“There was something before the Big Bang and that something is what we will have in our future.

“We have a universe that expands and expands, and all mass decays away, and in this crazy theory of mine, that remote future becomes the Big Bang of another aeon.

“So our Big Bang began with something which was the remote future of a previous aeon and there would have been similar black holes evaporating away, via Hawking evaporation, and they would produce these points in the sky, that I call Hawking Points.

“We are seeing them. These points are about eight times the diameter of the Moon and are slightly warmed up regions.

“There is pretty good evidence for at least six of these points.”

Within science, the concept is divisive.

However, many scientists believe that the universe is in a perpetual cycle in which it grows, shrinks in a “Big Crunch,” and then expands again before going through the Big Bang.
