Question

Why did the Big Bang happen? What triggered it?

Answer 1

That is a question that a large part of the scientific community is trying to answer.  We can trace the formation of the universe back to a tiny fraction of a second after the big bang at which time the universe was already expanding and cooling.  What caused the universe to start expanding is still the realm of hypothesis.

Answer 2

There was no "big bang". You have been duped.

Answer 3

good question...i don't know...what i would like to know is where did this swirling gas come from in the first place...considering there was meant to be nothing before the big bang!!!!>>>>....and if the universe is constantly expanding...what is it expanding into?????....sorry didn't mean to take over your question!!!!

Answer 4

The big bang happened because a finite potential triggered it's beginning.

  The question of what triggered it may be the most difficult part to answer.

  The fact that the potential was finite is what had to have triggered it,if the potential had been infinite it would have always remained and the universe would never have emerged.

  The trigger was a single quantum space-time pulse that evolved into the universe we see today.

Answer 8

If the Big Bang is correct (which I doubt) then before its fuzzy nanoscopic beginning someone (a Prime Observer) had to observe it into existence if the quantum mechanical concept of Shrodinger's Cat is correct.

Answer 9

Nobody knows yet. It is also not sure if we will ever find out.
