Large Hadron Collider

Definition

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator, designed to collide protons at near-light speeds to study fundamental particles and the forces that govern them. Its groundbreaking experiments have contributed to significant discoveries in particle physics, including the identification of the Higgs boson, which helps explain how particles acquire mass, and its implications extend to astrophysics by providing insights into the early universe and dark matter.

5 Must Know Facts For Your Next Test

1. The LHC consists of a 27-kilometer ring of superconducting magnets and detectors located underground near Geneva, Switzerland.
2. It was built by the European Organization for Nuclear Research (CERN) and began operations in 2008, with multiple upgrades since then to increase its capabilities.
3. The LHC can collide protons at energies of up to 13 TeV (teraelectronvolts), making it possible to recreate conditions similar to those just after the Big Bang.
4. Findings from LHC experiments have implications for theories beyond the Standard Model of particle physics, potentially shedding light on concepts like supersymmetry and extra dimensions.
5. The LHC's research has significant implications for cosmology, including understanding the nature of dark matter and exploring the fundamental structure of space and time.
