Wasn't trying to sound like a dikk my friend. Most people don't know much about astronomy/cosmology. The universe being infinitely small at one point is a fact (what we don't understand is what caused it to blow up like it did). If dark energy is what is causing our universe to continually expand at an accelerated rate, I would assume it was dark energy that caused the "big bang". It hasn't been scientifically proven that the universe will end, but there are many theories that make logical sense (stuff like the big crunch).
There goes that idea.
I always thought it could be like an accordion, it gets stretched out as far as it can go, then collapses back in on itself, then bursts out again and we start all over.
