I was reading a NY Times article on the lawsuit filed by Wagner and Sancho and amongst the usual doomsday predictions of black holes devouring the earth, strangelets turning the earth to strange matter etc... It made the claim that What kinds of things are they referring to? I mean... i know about the huge unlikelyhood of black holes causing trouble, and from what i understand strangelets would decay rather than destroy the earth as we know it. Is there anything else (other than dragons)? Here is a link to the article. And if anyone is willing... could you point me in the direction of some (introductory, if possible) websites/resources explaining QED & QCD as they relate to what will go on inside the LHC? I'm second year physics student - so i'm familiar with QM and various interpretations - but i haven't done anything on field theories. Of course if you're really feeling helpful, you could put some info in here for me!
