The Hadron Collider, specifically the Large Hadron Collider (LHC), is the world's largest and most powerful particle accelerator. Located near Geneva, Switzerland, it consists of a 27-kilometer ring of superconducting magnets and detectors. The LHC accelerates protons and heavy ions to nearly the speed of light, allowing scientists to collide them and study the resulting particles. These high-energy collisions help researchers explore fundamental questions about the universe, including the nature of dark matter and the origins of mass through the discovery of the Higgs boson in 2012. The LHC plays a crucial role in advancing our understanding of particle physics.
