The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator located at CERN in Switzerland. It consists of a 27-kilometer ring of superconducting magnets used to accelerate particles to nearly the speed of light and then collide them at various detectors. The LHC is used to study fundamental particles and forces of the universe by creating high-energy collisions and observing the resulting interactions. Research at the LHC has led to significant discoveries, such as the Higgs boson in 2012, and continues to provide valuable insights into the nature of the universe.
