End of the Universe?

I currently read an article about the end of the universe.  The article, which was entitled "The End of the Universe", was about, well...the end of the universe.  More specifically, it was about how the universe was going to end; either with a big bang, or a big crunch.  The article then goes on to state that the universe is going to keep expanding, until it begins a cold, dark, lifeless place.

The article then explains that if "The Big Crunch" never happens, then the Universe is predicted to keep expanding into a diffuse, dark nothingness.  Planets will detach from the universe and evaporate.  Protons are going to decay, all of the stars are going to run out of their fuel, and eventually all be engulfed into black holes.
