Did you know the Hale-Bopp comet will return 2,372 years from now, while in 50,000 years, Niagara Falls will disappear?

It's fascinating to learn how long certain materials will take to break down — the titanium in your MacBook will only start corroding after 100,000 years, while it will take 1 million years for humanity's glass products to disintegrate.

Doesn't really matter — according to this thing, we'll already be long extinct at that point. [BBC via Digg]
