The Large Hadron Collider in Europe, a.k.a, CERN, the most powerful particle accelerator ever built, is almost ready to start smashing some sub-atomic particles in the hunt for the theoretical Higgs boson and other mysteries of physics.
Some people are concerned about safety, however, and the risk of potentially creating a tiny black hole that would end life as we know it. Physicists argue about the true risk involved with the experiments planned for the LHC, but one thing is certain: No one really knows what will happen. As the New York Times pointed out, "the new collider could spit out man-eating dragons."
I think I'll go polish my battle-ax, just in case.
