Gravity pulled everything in the huge black hole of what would become the big bang. but what did it pull together? was there a big bang before the most recent big bang? will our universe be pulled together and "bang" again?

It's a possibility

Good questions!I'm not sure that gravity pulled everything in a huge black hole according to current theory,but the current model of how the universe formed is still being studied,and many questions are still being asked.Wikipedia could be a good start for further study:http://en.wikipedia.org/wiki/Big_bang

there are many theories about our big bang - as for if it will happen again, if the universe has enough matter the gravitational attraction between all the matter will be able to pull it all back together into what is called the big crunch (gee scienctist's are imaginative!) if it does not have this critical amount of mass the universe will go on expanding indefinitly.

Matter of fact, it seems as if the expansion is accelerating!

A recent idea is that that could be a statistical fluctuation, on a scale comparable to the Hubble horizon.

yeah Im not a fan of the big crunch theory.. but hey its a theory none-the-less

this may be because of what we are measuring. if we have 1 big, 1 small object......

LEGEND
0=mass
........=distance

0000 .................................................. ......................................
BIG............................................... .................................................. ....
object..................0.................................................. ...................
...........................small object............................................ ...................
............................we measure this.............................................. .........
.................................................. ....................00.......................
.................................................. ......................earth....................... ....

the small object would travel toward the big object. at the time we measure the small, it is going 6,000mph toward the big object, and, since we are attracted also, but not as much, we go 2,000mph. it is going relitivly 4,000 mph. we measure it next week. 6,600, to 2,200. its increasing! OMG! STOP. we are measuring the wrong thing. the big object is just accelarating the small. the big object is out of reach of our telescopes, so we cant see it. well, there may be many big objects around. so maybe eventually, alot of different black holes will form. ok, say be go away from the small to another object, thats closer.

0000 ..........6,000mph, increasing at 2,000 a week
BIG......................<----
object..................0
...........................small object...........6,000mph, increasing at 2,000 a week
............................we measure this.......................--->............................
.................................................. ....................00........................
.................................................. ......................earth....................... ....
.................................................. .................................... 0000....
.................................................. ...................................BIG object 2

then the 2 BIG objects come together, one with the earth joined to it, the other with the small object.
---->................................................. .....................................<------
00000.................................................. .....................00000
BIG object+small...................................... .......................BIG object+earth


they unite to form a black hole, black holes unite to make a big bang.

BIG objects + more BIG objects= black hole

000000000000000000
000000000000000000
BIG objects + more BIG objects= black hole

HUGE black hole= big bang Again!

[Boerseun]

Nope. You've lost me there somewhere.

Ok, put simply, it depends on what we are measuring. its kinda hard to explain other than my other post..
