All that now exists bursts from the singularity in a nano second and that wasn't an explosion? What was all of the light and heat and matter flying through space,

All that light and heat and matter weren't flying through anything. The Big Bang was an explosion OF space, not of things in space. ANd the universe is still expanding from the Big Bang. Things are getting farther apart, but not from moving through space. More space is coming into existence between things.

What did the singularity exist in, nothingness? If so what was the nothingness comprised of, because if nothingness existed it was comprised of something or a total absence of something to which it could be compared.

The Big Bang was an explosion OF space, not of things in space. ...More space is coming into existence between things.

And more time is coming into existence as well. Indeed, it is the expansion of time-space that moves time along. Stop the expansion of time-space and time would stop.

[Donald Rumsfeld Fan]

The Big Bang was an explosion OF space, not of things in space.

Space without matter is an oxymoron.
