World to be Swallowed By Black Hole...Or Dragon

There is a non-zero chance that the new particle accelerator being built in Switzerland could create a black hole that destroys the Earth.

"...anything created when the beams meet head-on in the collider will be born at rest relative to the laboratory and so will stick around and thus could create havoc.The new worries are about black holes, which, according to some variants of string theory, could appear at the collider."

Most of the scientists don't think it will actually occur, calling it "a long shot", but two crackpots in Hawaii have sued to stop construction.

Money quote:

"...there is some minuscule probability, he said, 'the Large Hadron Collider might make dragons that might eat us up.'"
