And it slips through our fingers

[Eomer of the Rohirrim]

I doubt it. Barring those wildcard asteroids, it's going to take a very long time for the world to fall apart or be pulled apart or whatever.

The human race, though, might well be reaching its end. I don't think we're going to seriously challenge the dinosaurs in that regard. But it will not fade away rather than burn out; it will just fade away.

I don't agree that the human race reached a high point and then fell from grace. I think that it just shifted and morphed slightly. So there will be nothing tragic about the end of human beings. It's going to be very unromantic.
