<human>:  Why is it called the Large Hadron Collider?
<bot>: That’s because the Large Hadron Collider is a large particle collider. It is the largest particle accelerator in the world, and it was built to study the properties of particles called hadrons. The name is a play on words because “hadron” is a Greek word that means “proton”. The Large Hadron Collider is a 17 mile ring of superconducting magnets that accelerate protons to nearly the speed of light, and then smash them together to create the Higgs boson, which is the most massive particle ever found.
