Quote:Extrapolation of the expansion of the universe backwards in time using general relativity yields an infinite density and temperature at a finite time in the past.[13] This singularity signals the breakdown of general relativity and thus, all the laws of physics.
No, these are not accepted facts. This is just the extent of our understanding.

What came before the big bang?
Quote:The trouble is, our understanding of space-time, and gravity in particular, is built from Einstein’s equations of general relativity, whereas the extreme conditions of the very early universe can only be described by quantum mechanics. No one knows how to reconcile the two to take us further back. “The rules we have simply don’t work in that regime,” says Carlo Contaldi at Imperial College London. “Nothing makes sense any more.”
That’s a problem for our origin story. Did time begin with the big bang? Or was there an epoch before it?
Some insist that if we rewind the universe far enough, time just stops.But Lee Smolin of the Perimeter Institute for Theoretical Physics in Waterloo, Canada, is having none of it.
“It’s a cute idea but there’s not much evidence for it,” he says. In fact, Smolin wants to see the idea that the universe has a starting point dropped entirely. We can only hope to explain why our universe is the way it is, he says, if there was something before the big bang. It’s about cause and effect; to arrive at satisfying explanations for why things are as they are, we draw on previous events that led to the conditions we see.
