Timbo - There is a theory that dark energy will eventually overcome gravity completely. So after the stars start receding from each other, the atoms of Voyager 1 and 2 will also do the same. Personally I find that sad, so I'm rooting for a gravity come-back, then a big crunch as everything collapses back ready for the next big bang. I am a romantic though.
