The Big Bang theory is the mysterious question that had been actual before and will be actual in future until the scientists find out the real and precise definition. It is the leading explanation about how the universe began. It is supposed to say the universe as we know started with a small singularity, then inflated over the next 13.8 billion years to the cosmos that we know today. By the way, let’s pass on the deeper question “But what happened before the Big Bang?”. The famous physicist Stephen Hawking gives a definition to this question, which he gave in an interview with his colleague scientist, Neil de Grasse Tyson. Hawking speaks about these ideas and others on the series finale of Tyson’s “StarTalk” TV show. Now the question “What was there before there was anything?”. Stephen Hawking focuses on the “no-boundary” theory. “The boundary condition of the universe…is that it has no boundary,” he says. In accordance with TechTimes, Hawking declares 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.” Hawking also 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.”
This is not the first time that Hawking discusses this theory, he has also a documentary film connected whit this topic. In that film Stephen Hawking, James Hartle and Thomas Hertog explain their model of the early universe.
