[QUOTE="freyar, post: 4561032, member: 40227"] To be absolutely fair, about 10-11 years ago there was a model proposed in which you would expect the LHC to create mini-black holes. However, it is also absolutely true that the recent discussion of black holes at the LHC has been driven by a few fanatics who don't know the science. In fact, I spoke to one of the people who invented that model about a week and a half ago, and he really doesn't believe it to be correct. So, yes, it's certainly not expected to create black holes. Treebore, I don't know if this will be reassuring or not, but, on the extremely off chance that the LHC does create black holes, it would be very difficult to tell them apart from any of the other possible particles it could create. In particular, as we know from cosmic rays (as Mustrum mentioned above), they either decay extremely rapidly (which is what one would expect from all theoretical considerations) or interact with normal stuff very weakly -- to the point that they'd just go flying off into space pretty much completely unimpeded by the earth or anything on it. There wouldn't be any way to try to capture them, grow them, or control them. They'd just be gone. Another point is the human one: none of the people involved in particle physics, either theory or experiment, want to destroy the earth or civilization. I know and/or have met a number of these scientists, and these are people with kids, hobbies, and all kinds of attachments. There has been an extreme amount of care taken with this experiment.
