Don't worry fellow humans, I'm a time traveler from 2343 a.d. and I just wanted the worried people out there to know that this experiment is harmless. After eight months in operation, a new exotic particle will be found (no, not Higgs Boson, which BTW, doesn't really exist). No black holes whatsoever, at least not right now (these were created and destroyed in lab for the first time in 2157 a.d., and all went well too). BTW, instead of wasting so much time in theoretical physics, just conjuring theories, you might want to change your approach and worry more about direct observations of reality instead of theorizations. Also, you should revise some misconcepts that you have, specially some very basic ones about how electricity works and the relationship between magnetism and "gravity" (or as we call it today, "graviticity"). A hint:study the stuff that Edward Leedskalnin has left behind, and no, his "Sweet Sixteen" is not a girl, it's a symbolic reference to the key concept in electrodynamics.
That's as much as I can say without changing the future... or making it too easy =)
