It is a good thing that we won't be around in 50 billion years. Then again... we won't be around in 3-4 billion years when our own Sun dies. That whole expansion thing will increase the sun to a size larger than our orbital radius, engulfing the planet. If somehow that doesn't kill us, it will then shrink and shrink and shrink until the energy is contained in too small of an area, at which time it will explode. Or, it will just go dark and we'd freeze. I forget which category our Sun falls into.

On a seperate note, I greatly enjoy the fact that I know and understand concepts such as Planck time/length, zero point, singularity, cosmic foam...
