Sorry to bug you all, but I have a question to ask. I have a bit of a worrying problem, so when I first heard about the LHC, some of the fear mongering got to me. However, after some research, my worrying nearly ceased. However, I ran into this paper today, and it says there may be a bit of a risk with the LHC. I don't have the knowledge to assess the paper, could someone please explain it to me and tell me if there's any reason to worry? Again, sorry for disturbing a forum full of very intelligent people with my (perhaps trivial) worries.
