Subject: Is perpetual motion possible for the entire Universe?

Hi, I'm just a high school student interested in Astronomy (I'm learning 
from books I can get at the library).  I'm also thinking beyond what I 
read.  So, I came up with something.

Assuming that nothing can exist outside of the universe as we perceive it, 
is it possible for the universe to have, what I think would be considered, 
perpetual motion?  Assume that there was a Big Bang, and there will be a 
Big Crunch.  Would it be possible for the Big Crunch to set off another 
Big Bang and create another universe from the impact on itself?  It can't 
lose energy because there is nothing to lose it to, can it?
