Actually according to Hawkings law on space.... our galaxy will end yes but the universe will never end as it is endless so has no end. As one galaxy dies in the fallout another is created and so on and so on... so there is always life at some point just not in our galaxy so you'l be reincarnated as an alien.

Besides we're all made of star dust anyway.... we're made of the exact smae stuff earth is, mars, jupiter, the sun.... etc
