Hi, I have no academic grounding in advanced physics, but I have read a lot of the popular books on physics, and am generally interested in it. (In a couple of years that's probably what I'll learn in college). Anyway, there are people who are afraid that when the LHC goes on this summer we might accidentally create a black hole and destroy the planet. I don't have the mathematics to back this up, but: If we do create a singularity in CERN we will be inside the event horizon, and so close to the singularity itself that we will feel the effects of infinite time dilation. So if we did create a black hole, we won't know about it because time has ceased to have a meaning for us. Does that make any sense?
