What is the origin of time?
According to the general theory of relativity, space, or the universe, emerged in the Big Bang some 13.7 billion years ago. “In the theory of relativity, the concept of time begins with the Big Bang the same way as parallels of latitude begin at the North Pole.
What happened at the beginning of time?
Rather, the universe, and time itself, had a beginning in the Big Bang, about 15 billion years ago. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down.
Was there no time before the Big Bang?
However there are many other theoretical physicists that do not say that there was no time before the Big Bang. The problem is that the equations of General Relativity say that at T=0 of the big bang there is a singularity that fills all space. All a singularity means is that the equations we are using must be wrong at that time.
What did Stephen Hawking say about the Big Bang theory?
According to 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.”
Was there a big bang that produced something from nothing?
Essentially, “there was never a Big Bang that produced something from nothing. It just seemed that way from mankind’s point of perspective.” In 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.
Why can’t we see beyond the radius of the Big Bang?
We can’t see beyond that radius, wherever we’re located. For many reasons, cosmologists think the early Universe underwent inflation: an incredibly rapid expansion right after the Big Bang. As the Universe expanded, it also cooled, so in the distant past, it was hotter, more dense, and opaque to all forms of light.
