If you believe in the big bang theory (witch i don't) you must assume that after the explosion that the volicity of the expended matter travels at a constant. So then for the big bang theory to be plausable you must asume that the outer most pieces of the big bang are the smallest, while those closest to the center are the largest, so that the gravity of the matter closest to center will eventually atract the outer most matter back. This in essence is the cycle of the universe.

The way scientist try to prove the big bang theory is by showing how that stars in each galaxy are relative in size and that are descending/acsending in size in a circular motion from an origin.

The big bang theory has a lot of wholes, and i am sure future generations will laugh at our theories. Like how people thought the earth was flat, or in the center of the universe, or how the planets rotated in circular motion, etc.

The string theory seems more possible, but it still has some questions that need to be answer. In a string theory there are multipe universes, and black holes are gateways/portal holes to other universe. It also say that there seems to me know end to the universe, but when you think you are travling straight (at the enge of the universe) you are actually travelling around the wall, kind of hard to explain with no pics.
