So if the universe was @ 1 single super compressed point, then it exploded and created the universe we have here today,
Wouldnt all the matter shot out of the super compressed point all be going away from each other and never have the possibility of intersection?

does it make sense or not? im sure this question has already been answered, i just havent found the answer.

i would guess that colision of matter and gravational pull from mass of large objects effect the movement

the theory isnt that matter did a completely perfect spherical nova; im sure that it was no where near a flawless explosion.

If the universe had expanded with a uniform mass distribution, yes, it never would have "intersected" as you put it. Pockets of gas wouldn't have separated themselves out from each other because there would be equal gravitational forces in all directions. However, because there was NOT a uniform mass distribution, the gases were more pulled in some directions than they were in others, and so eventually the matter separated itself into galaxies.

If that didn't answer your question, let me know. the URL didn't create a link and I'm short on time atm so I didn't have the time to fool around with it.

1st , there was no matter in the " big bang "
matter was created later

2nd , the distribution was not uniform (if it was , you would be right , and gravity would have been equal everywhere , and no clumping of matter would have occured )

nice sig

What if the big bang was really only a single gigantic star that went supernova?

and our universe is only one of billions of those?

this

something exploded therefore you could call what exploded "matter", even if its not the same matter or in the same form as the matter we see today


matter randomly appearing out of nowhere from nothing is ridiculous

It's more accurate to say mass-energy than matter. Anyone who would make a claim that there was nothing and then it exploded does not have an accurate understanding of the Big Bang theory.

first lets answer this: in a pure vacuum matter appears and disappears continously.

when the big bang occured (some 13 billion years ago approximately) the universe as we know it was created, what we have to understand, wich i admit is VERY hard is that space did not even exist before that, it was a zero dimensional space.
in the big bang it was matter and anti-matter that appeared (the building blocks of neutrons and positrons etc etc) the smallest imaginable matter. first was the "inflation" of the universe wich appeared at a far higher speed than the speed of light, imagine something that is smaller than an atom blowing up to the size of milkyway in matter of seconds, what we can see of the universe is only a small fraction of how big it really is, 13 billion light years in <--that direction and 13 billion light years in that direction, well all directions.

Some trivia at the end, i couldnt help myself

now this is not so easy to understand, the space we live in is very strange in some senses.
for example how much matter it is in an atom compared the space it occupies, if we take all neutrons and positrons from every living human being on earth and we put them next to eachother in a small ball, it would be no bigger than an apple, or a tennis ball. it would still have the same mass. (still not a black hole) if we would take earth and compress it to a black hole its event horizon would be 15centimeters across
