Well for a regular quantum fluctuation to become a Big Bang it has to stay in existence for a longer than normal period of time allowing for it to inflate

Putting that in numbers, how sparse does the universe [or some part of it] have to get?

Probably down to Planck measures.

As can be seen in my other threads, I am not the strongest advocate of the big bang, but as I understand what is being asserted by those who believe, the essence of the big bang's occurrence is that it is the one fluctuation that lasted much longer than an average garden variety fluctuation (I still am not sure what is fluctuating where pre-big-bang conditions are considered). It expanded rapidly in search of the missing anti-matter in an attempt to maintain charge parity which it still hasn't found. What's another epicycle or two?

Dear fellow contributors to this most metaphysical of threads,
Not only have I read and re-read this enlightening thread, and wrote and re-wrote an appreciative precis of catapulting ideas, but have decided to pose a triad of questions while my pet theory(and a theory about pets) and a peculiar assumption lurk in the blackboard of my mind...
Is "Existence is eternal" contradicted by science? Could ultimate reality be infinite? Could the universe be absolutely insignificant, yet undying like everything else? Yr obt srvt, Hyginus

Isn't there a theory that the Big Bang was caused by two universes colliding? That makes more sense than the theory that there was nothing at all before our universe. I can cope with other universes but not with the idea of NOTHING!
