2. The scientists say they don't really know what's going to happen, that's why they are doing it.
Well, yeah - that's why it's called
science. And while they don't know
exactly what's going to happen, they do know that it's
not going to destroy the world. I don't know exactly what's going to happen with my latest experimental brew either...
3. One member of the team said on TV the other day, "The chances of creating a black hole are less than one in a hundred."
Yes, there is a small possibility that the LHC could create micro black holes. However, the same physics also means that any micro black holes would evaporate almost instantaneously in a small but fascinating burst of
Hawking radiation. If the physics is wrong on the evaporation part, then the LHC won't be able to create a black hole anyway. The two things are inseparable.
Really folks, there's nothing to worry about. It's just the usual story of the media preferring to run with the nonsensical but entertaining rantings of a bunch of crazies who don't understand what they're talking about, rather than actually deal with real science. Science is hard and doesn't sell newspapers. Mindless panic is easy, and
does sell newspapers.
