What Could Have Possibly Triggered the Big Bang?

triggering the big bang!

if we consider singularity as the starting point of our universe...what could have possibly triggered the big bang?

We don't know. All we know is that the available evidence points to the universe once being in a very dense very hot state, after which it expanded. At these densities and temperatures General Relativity, and most known physics, breaks down and are unusable. We quite simply, don't know.

What confuses me is that space and time are supposed to have come into existence at the Big Bang. Some claim that the Big Bang happened because of a quantum fluctuation. But how could a fluctuation occur if there was no prior flux in which it could occur? Or, are quantum fluctuations independent of time in some kind of strange way?

will the experiments aimed @ trying to recreate the big bang help us understand the cause?...or will they reflect on the effect only?
