According to quantum physics, particles do arise out of the void all the time. Virtual particle pairs, a particle and an anti-particle, arise out of the vacuum and then recombine and disappear in immeasurably short periods of time. This is called a vacuum fluctuation. The larger the particle, the less statistically likely it is to appear, and the shorter the period of time that it lasts. So there is a remote, but statisticaly possible chance that a virtual elephant might appear in your living room, but it would be gone so quickly that it wouldn't really have any effect.

One model for the Big Bang holds that the Universe arose as a vacuum fluctuation. It was an incredibly massive singularity that arose out of the vacuum. Ordinarily such a massive vacuum fluctuation would reconcile its virtual particle pairs in an unimaginabley short period of time and disappear back into the void, but because of the density and pressure, the singularity curved space-time and triggered a massive inflation of space-time. During this super inflation, the virtual particle pairs become irreconcilably separated in space and a stable universe resulted which was not going to instantaneously fall back into oblivion.

So it is not right to say that there is "absolutely no explanation as to how this infinitely dense blob of matter just happened to appear in the middle of a great void of time and space." It arose as a vacuum fluctuation.
dragonrider Reviewed by dragonrider on . wtf happened before the big bang? i was high one day and was thinking about the big bang and stuff. and thought what happened before the big bang? scientist always talk about the big bang and everything that happened after that, but none talk about before the big bang?
