And you thought the economy was bad!

Phil Plait examines the ways the Universe could wipe out mankind. I'm not worried. I'm pretty sure I'll die on my own before that.

But I can't believe that mortality is more than a tiny slice of our existence. Science itself admits to a gigantic blind spot created by the speed of light and is only now beginning to recognize the existence of other dimensions, even as it denies that there could intelligent beings there. Intelligence cleaves to intelligence and seeks its own kind, and while we are any intelligent species, surely there are more intelligent ones or perhaps more advanced versions of our own.
