The Large Hardon Collider is a giant particle accelerator: a 17-mile-long tunnel beneath Switzerland and France. With it, scientists hope to isolate the Higgs boson, the particle that could explain mass. Some worry that the Hardon Collider is too big and could create a black hole that, while awesome, would destroy Earth. Is such a huge Hardon Collider worth it? Why are you laughing? Oh. Oh. I see. My mistake. I meant to say “Large Erection Collider.”
