However the only thing i know of that would be able to pack in so much shit to create a big enough bang would be a black hole, but that would be sucking shit in. Is it a proven theory about white holes? you know the other end of a black hole where everything comes out the size of a pea. Maybe one of those is at the source.

"Dark Energy" is now the leading candidate
for agent of accelerated expansion:

New evidence has confirmed that the expansion of the universe is accelerating under the influence of a gravitationally repulsive form of energy that makes up two-thirds of the cosmos
It is an irony of nature that the most abundant form of energy in the universe is also the most mysterious. Since the breakthrough discovery that the cosmic expansion is accelerating, a consistent picture has emerged indicating that two-thirds of the cosmos is made of "dark energy" - some sort of gravitationally repulsive material...

I do not think this dark energy stuff is connected
with any of the lesser cosmic explosions which
have followed the Big Bang, or with singularities.
