On Reality Carnival I saw this mind-bending timeline that projects future cosmic events from the year 10,000 until the theoretical end of the Universe as we know it.
Of course, I don't really care what happens to the universe after I die since I won't experience it.
It's interesting to think about, though, how long into the future mankind will be able to extend our brief cosmic existence. To do so, we have to extend our presence outside the solar system so we're not at the mercy of what happens to this particular planet. At the rate we're going, it may take a looong time to begin traveling between the stars.
However, there's also the possibility that both the ancient gnostics & South Park were right- that Earth is a cosmic prison that human beings are trapped in... FOREVER.
There's also a section of the website that outlines the history of the known universe.
