If it (LHC) does destroy the world, there’s no-one in the future to travel back in time to do anything about it. It’s all a bit Back to the Future really.
It’s part of this whole mystery about the machine — people are willing to believe anything. Physicists sometimes shoot themselves in the foot by not saying, ‘We won’t destroy the world with black holes,’ because they work on probability. Saying, ‘This won’t happen,’ is just not ingrained into them. -Dr Paul Jackson, Particle Physicist (via Gizmodo)
