I tend to go for the heat death option which will be around 22 billion years in the future and total matter dispersion 100 million after that. Or a steady state option. Depends on how much dark matter there is, causing gravitational collapse, or how much dark energy there is, causing increased expansion.

I wish Earth's future looked as long. :o
