Actually this is why scientists need to start hiring PR more. the "Big Bang" doesn't even come close to describing what the theory is, it only describes the end of the theory. It starts out as a massive amount of particles without form then gathers, as the center grows denser the gravitational field is suppose to get stronger then once most of it is gathered into a solid mass it gets torn apart from the extreme gravity. Though you are right, that theory is one of the less logical of them all, it's sad really that people aren't looking into the lesser known ones since some of them (talking strictly scientific here) are much more logical and easily tested. The only one that is REALLY out there (again a lesser known one) is the tear theory, but that breaks every law of physics and even logic known to us and therefore was tossed out rather quickly.
