Again, my limited understanding of the big bang theory is that it created the universe as we know it (at least once inflation had ended), and that a number of physical laws were set at that time. Or, at least we cannot know if these conditions were created then or carried over from some earlier existence. If you take S. Hawking's assertion that contemplation of what came before the Big Bang was meaningless, because time did not exist till the big bang at face value, then anything that incoproates time also did not exist till the big bang. Can you describe momentum without time?KitemanSA wrote:Would you explain this statement please? You seem to be stating that somehow momentum was spontaneously created at the big bang? Is that your meaning? If so, why do you think that?D Tibbets wrote:Perhaps not in the mundane current universe, but this apparently happened in the big bang/ inflation, unless you assume something existed in some parent universe/ set of dimensions that led to our own.kcdodd wrote:.....But, you still cannot spontaneously create momentum. It ultimately comes from whatever is pushing on the particle to begin with.
