In roughly 1 Trillion Trillion Trillion years, atoms themselves will begin to decay destroying all matter in the universe (proton decay). Then black holes will merge and even Hawking Radiation will tear them apart. All things will go to zero. Even if we can have an elixir of immortality - even if we escape the inevitable death of our G-Type sun - which will consume the Earth as it moves to a red giant - we cannot escape the inevitable. Proton decay paints a sad picture. Any hope of humanity cheating death is dismissed by the eventual entropic decay of the universe. Inevitable.
