<human>:  Why is it called the Large Hadron Collider?
<bot>: The Large Hadron Collider is named after the hadron, a fundamental particle of matter. Hadrons are the most common form of matter, and are made up of quarks and gluons. The LHC is the world’s largest and highest-energy particle accelerator, and is located at the European Organization for Nuclear Research (CERN). It is designed to smash particles together at very high speeds, in order to study the properties of matter at extremely high energy densities.
