";s:4:"text";s:1856:" Reports of the death of the Big Bang have been greatly exaggerated.
Nothing we observe today existed prior to … Because this expansion happened everywhere, the term “the center of the universe” doesn’t really mean anything. The universe is in a constant state of change. The beginning of real time, would have been a singularity, at which the laws of physics would have broken down. The reason that the universe did not collapse, as Newton's and Einstein's equations said it might, is that it had been expanding from the moment of its creation. The beginning of the universe, the start of space, and even the initial start of time itself. The conclusion of this lecture is that the universe has not existed forever.
The expanding universe is finite in both time and space.
At the same time, our universe may not have a beginning or end. Indeed, we could say that each observer is at the center of their own universe. This was the singular start to everything that exists. According to the standard Big Bang model, the universe was born during a period of inflation that began about 13.8 billion years ago. Scientists believe that our universe began with one enormous explosion of energy and light, which we now call the Big Bang.
This was not like an explosion into empty space, but expansion of space … Initially concentrated in a very small point, the universe expanded outwards rapidly with enormous energy.
