Stephen Hawking has revealed his answer to one of society's most mind-boggling questions during a chat with astrophysicist Neil deGrasse Tyson on Star Talk. In other words, what happened before the moment the universe began?
"The boundary condition of the Universe ... is that it has no boundaries", said Hawking.
"Events before the Big Bang are simply not defined, because it is impossible to measure what happened".

In order to comprehend the Big Bang, scientists created various mathematical models and formulas as the instruments scientists use today are incapable of looking back to the origin of the universe. If the Big Bang occurred due to the explosion of something then what was that and where that thing came from? For him, the imaginary time works like a fourth direction of Space. Moving further, he also dictated how time was distorted during the period of singularity where it was reaching closer to "nothing" but never become it.
"One can regard imaginary and real-time beginning at the South Pole".
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.
According to Hawking, the laws of physics and time cease to function inside that tiny particle of heat and energy.
Scientists still can't for sure determine what triggered The Big Bang and the beginning of the universe.
The 76-year-old Hawking explained that there can be "nothing south of the South Pole" as a basis for his argument that claimed that nothing existed before the big bang.
During one of his lectures, Hawking had stated that there are no observable consequences from what occurred before the Big Bang.
To better understand this theory, Hawking proposes to "rewind" the development of the Universe.
