This site begins "Destroying the Earth is harder than you may have been led to believe..." and it continues on to list the top ten ways to destroy the earth. Options include "Blown up by matter/anti-matter reaction," "Destroyed by vaccum energy detonation," and the ever-popular "Sucked in to a giant black hole." Thanks for the post, Sam's archive.

And thanks to Clive Thompson's terrific blog, Collision Detection, of which you'll see more of on here soon.
