You are thinking of Entropy - the universe tends to disorder, because energy is required to create order. The Heat Death of the Universe occurs because for heat to be transferred from one object to another, there must be a temperature gradient - heat moves from warm objects to colder objects (never the other way around). Over time, everything would eventually become the same temperature, so heat could no longer be transferred. This would be.....bad.

At the instant the big bang was formed it would have had to be uniform in temperature/pressure because it was a singularity. It expanded because the area 'outside' was zero temperature/energy. Some galaxies are heading toward each other and some have even collided?? Will it expand forever? Only if it contains infinite energy because expansion represents increase in potential energy due to gravity. This is unless at some point there is a limit to the reach of gravity.
