A big machine that could create mini black holes and destroy the Earth, but physicists say it's totally safe, even though no one knows what a black hole is.
The LHC might turn Earth into a black hole, but scientists think it's totally safe, even though they've never seen a black hole before.
If the LHC makes black holes, it might take Earth with it, but the scientists are just trying to get a raise.
They spent billions on the LHC, but it might also be the reason we all die in a black hole.
