For a more accurate, and interesting, take on the Large Hadron Collider check out jgordon's post on the subject and the discussion there. As jgordon says, "The thing is, the people who would know best whether or not a supercollider is at all likely to start the apocalypse—they're they people working on the collider. And they point out the at the sort of collisions that they hope to observe in the LHC are happening all the time in space around earth, and so far earth has been okay." The likelihood that anything like this would happen is so minimal I'm more worried about Earth being eaten by a giant space squid than a problem with the LHC.

Joe, dude. stop insultin my videos. i think their interesting. Its a black hole. It would suck everything up. End of story.

Well, ok Joe! i know that to create a black whole, the experiment would have to go WAY farther than unstabble. c ya!
