Does history repeat itself? (Big bang theory)?

[Ascirc]

From what I know, the big bang theory says that (to put it simply) there was a huge hunk of mass, and it exploded. Now all of that mass is the tangible stuff in the universe.

And...eventually all of that mass goes back to a center point, joins up and forms another hunk of mass, then it explodes again. No mass lost, no mass gained. Because none of it was lost or gained, and it's going to go back to the same place it started, doesn't that mean that every action we do in life has already been done an infinite amount of times?

I'm probably wrong on the big-bang theory, so please fill me in if I'm wrong The idea makes sense though: if all the matter went back to where it started, and with the idea that you can't loose matter/gain it, it's going to explode the same way, and everything forms the same way. I will be born the same year, Jimi Hendrix will die young, and the Red Sox will win the world series in 2004.

Right?
