The LHC’s maximum energy is only 6500 GeV. The smallest experiment which could even hypothetically destroy us all (Higgs Boson Metastability, which only fits one of several predicted models of the Higgs Boson, but experiments to date have not helped narrow down which model is corect) would require around 100,000,000,000 GeV, which in turn requires a collider with a mass greater than Earth and power almost equal to the sun’s output. Basically, you need a
Dyson Sphere just to even toy with the idea ... Read even more
