Here’s another of the wonderful TED talks, this time Brian Cox talking about the Large Hadron Collider (LHC). The LHC is the $10 billion atom smasher that got powered up a couple of weeks back, spun some protons around a circular track 27km long, and then broke down. They didn’t even get to do any smashing. Some claimed that the LHC could create a black hole that would destroy the Earth. Well, that possibility is now postponed until next year now that they have to warm the track back up from -271 degrees celsius, go in and finish repairs, then cool it back down again. Oh, there isn’t really any possibility that it will create a black hole that will destroy Earth.
