"The Big Bang theory is an attempt to describe the creation and evolution of the universe. The theory appears to match observations, and the theoretical physics appear to hold back through time to within a tiny fraction of a second after the creation of the Big Bang. Beyond that the theory cannot explain how the Big Bang singularity came into existence. See The Big Bang Theory Indeed, it is really pointless to attempt to go back beyond the Big Bang, it is meaningless to ask what came 'before' because there is no 'before'. Time itself came into existence with the Big Bang.
Stephen Hawking in 'A Brief History of Time' describes how time and energy came into existence with the creation of the Big Bang, but that the laws of science break down at the singularity preventing us from looking further back in time. As far as the Big Bang theory is concerned it is meaningless to look back beyond the Big Bang, nothing existed. Perhaps so, but it's very unsatisfactory to have a theory of the creation and evolution of the universe that does not explain where the universe, the Big Bang, actually came from, it must have come from something. Or must it?"
Does anybody know?
