According to the latest comments made by Professor Stephen Hawking, Before the Big Bang, time existed in a bent state that was distorted along another dimension.
The famous theoretical physicist Stephen Hawking has an answer to the enigma of what existed before the Big Bang, the beginning of the Universe, 13,800 million years ago.
In an interview with his colleague Neil deGrasse Tyson in the TV show ‘Star Talk‘ broadcasted on the National Geographic Channel, Hawking explained what existed before the universe.
“The boundary condition of the universe…is that it has no boundary,” Hawking said.
According to this theory, the history of the universe is not a flat line but a four-dimensional, curved object, “just as the surface of the Earth, but with two more dimensions,” Hawking said. As explained by Professor Hawking, the Big Bang was practically the formation as we today understand as ‘time,’ since this event, 13,800 million years ago, broke the known laws of physics. It also means that anything that may have existed before the event, simply cannot be applied to our understanding of time and existence.
In other words, Professor Hawking argues that there isn’t really anything such as ‘a time before the big bang’.
Professor Hawking added that one can regard imaginary and normal space-time as beginning at Earth’s south pole – a point where the normal laws of physics hold.
However, the world-renowned astrophysicist explained; “There is nothing south of the South Pole, so there was nothing around before the Big Bang.”
To better understand what Professor Hawking means, you would have to imagine a remote control that controls the universe and press the Rewind button.
The universe is constantly expanding.
As you go back in time, the universe contracts.
Rewinding to the Big Bang, the entire universe is reduced to the size of a single atom, Hawking said.
This subatomic ball of everything is known as the singularity.
Within this small and enormous mass of heat and energy, the laws of physics and time as we know them cease to function.
In other words, time as we understand it literally did not exist before the universe began to expand.
On the contrary, the arrow of time contracts infinitely as the universe gets smaller and smaller and never reaches a clear starting point.
As noted by TechTimes, Hawking says during the show that before the Big Bang, time was bent — “It was always reaching closer to nothing but didn’t become nothing,” according to the article. Essentially, “there was never a Big Bang that produced something from nothing. It just seemed that way from mankind’s point of perspective.”
In a lecture on the no-boundary proposal, Hawking wrote: “Events before the Big Bang are simply not defined because there’s no way one could measure what happened at them. Since events before the Big Bang have no observational consequences, one may as well cut them out of the theory, and say that time began at the Big Bang,” reports Space.com.
