Okay, I'm a Senior in Highschool and I still rarely know about the Big Bang Theory. I never really payed attention to that portion of science. I rarely payed attention to Science period and now I regret it cause I'm starting to find it extremely interesting.

All I know about the Big Bang is that there was actually no Bang... There was just a Expansion. The past hour I've been searching the internet over this and so far ive got that it was composed of singularities

The big bang theory doesnt really do a good job of explaining the origin of matter and the universe really at all. It may pose an idea for how things became the way they are in relation in the universe, but not their origin.

Essentially, the big bang theory is just a compression of matter so powerfully that it exploded and is what is composing our universe.

However i find it hard to subscribe to the big bang theory, or the bible, or just about any other reason for our existance, because there is absolutly no way we are anywhere close to such an answer.

its not so much about believing it but more of understanding it. if you understand why its the main theory than thats all you can do until we advance.

The big bang theory doesn't explain the actual origin of the universe at all. It is simply a theory of how the universe evolved after the first second or so. All the matter/energy in the universe was at one time compressed into a singularity and then rapidly expanded at unbelievable speeds. After some period of time the universe cooled enough for matter to start forming. As for the singularity it's supposed to be a point of infinite density, but all that really means is we don't know what was happening then. We have even pretty much no idea about what happened "before" the big bang.

If your interested in this sort of thing you should try physicsforums.com. There's all kinds of physics topics there to read about and discuss, and people are pretty well informed over there. JSP doesn't seem to be the greatest place if your looking for science related things.

To truly understand the big bang how it started this "Expansion" you must understand String theory. Lmk if your interested.

Energy can produce matter. That's where the matter came from, and the big bang explains the expansion.

doesn't really change what hes saying. still leaves a gap for where the energy came from.

The energy came from a different parallel universe.

However we dont know that or have any means of knowing such a thing.

If we are to use that argument, would must realize that it is also fundamentally flawed by what is it that its trying to explain. Where would the mass have came from in that parallel universe? Another one? Then it would be sufficent to say that all universes are in a perpetual cycle and would thus have no logical origin. Since we could and do not have the means of knowing such origins, then you could make the same assertion which will be self defeating.

I dont see why it is so hard to believe that everything just exists with no beginning, and thus would be infinite and have no end to existance. Has anyone stopped to consider that possibility?

On such philsophical grounds, "before" existance, nothing existed. Then since the concept of time did not exist either, then the idea of nothing before existance, would also be self defeating by definition since time is an illusion within existance itself. Therefore one might conclude that existance has always existed, and there is no origin.

If the big bang is out to explain how the universe has emerged the way that it is, i would be much more inclinded to believe it. Though all i've learned about the big bang is that it is used to explain the origin of the universe and everything in it; not the state that it is currently in. So maybe I dont know what the big bang is really all about

well its mostly just a common misunderstanding about what the theory is currently there to explain. its kind of like a painting thats halfway done you can see the colors but you still dont know what you are looking at.
