CERN Large Hadron Collider

Definition

The CERN Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator, located at the European Organization for Nuclear Research (CERN) in Switzerland. It was built to explore fundamental questions about the universe, including the properties of the Higgs boson and the mechanisms behind mass generation. By colliding protons at nearly the speed of light, the LHC provides insights into high-energy physics and the underlying structure of matter.
