As used by cosmologists, the term Big Bang generally refers to the idea that the Universe has expanded from a primordial hot and dense initial condition at some finite time in the past (best available measurements in 2009 suggest that the initial conditions occurred around 13.3 to 13.9 billion years ago) and continues to expand to this day. -en.wikipedia.org/wiki/Big_Bang

basically, it says that the universe started as a really big mass of stuff, then it exploded suddenly, and its still spreading out to this day.

it was a singulartity (what they call it) A dense HOT HOT HOT small peice of matter. smaller than a microscopic organism. it expanded. (Think of it as a balloon, it gets bigger and bigger and bigger. It forms our universe. Planets, Galaxies, stars.) all from that one "singularity". where it came from? some say it was just there. My opinoin is God. DUHHH! this balloon has never popped or began to contrct because God never told the universe to stop expanding. Our universe is huge! (especially if it was made 13.3 BILLION years ago)
