I believe the current theory is that there was a point, infinitely small containing everything. The Big Bang caused this point of matter to accelerate in all directions outward.Technopunk said:Can someone, for simplicity's sake, clarify the big bang theory for me...
Was it
"There was this big empty nothing, and then the nothing went BANG, and tossed stuff into the universe"
or
"There was a boatload of stuff hanging out in one place surrounded by a bunch of nothing and the stuff went BANG and tossed all the stuff apart into the universe"
or
"We dunno, but something went BANG and now there is a Universe"
Thanks
Oh, also... How much of what we know about it is hard scientific facts, and how much a theory?
Most of this explanation of the universe is supported by evidence. Stars and Galaxies are expanding outward. The further away, the faster they are moving. Extrapolating backward and we can deterimine that all measurable matter originated from a single point.
As we experiment with how matter and energy behave as we backtrack from the present, we have gained understanding about the makeup of the universe.
There is still much we don't know. But what we do know, is known with a pretty high confidence level.
