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. According to Hawking, the laws of physics and time cease to function inside that tiny particle of heat and energy. The ordinary real time as we know now shrinks infinitely as the universe becomes ever smaller but never reaches a definable starting point.
Hawking argued that before the Big Bang real ordinary time was replaced by imaginary time and was in a bent form, state run news agency Xinhua reported. “It was always reaching closer to nothing but didn’t become nothing,” said Hawking. To help people better understand the abstract and confusing state, the physicist drew an analogy between the distorted time with Ancient Greek philosopher Euclid’s theory of space-time, a closed surface without end.
“One can regard imaginary and real time beginning at the South Pole. There is nothing south of the South Pole, so there was nothing around before the Big Bang,” Hawking said. “There was never a Big Bang that produced something from nothing. It just seemed that way from mankind’s perspective,” Hawking said. He said that a lot of what we believe is derived from a human-centric perspective, which might limit the scope of human knowledge of the world.
