Big bang tunnel cern

CERN's Large Hadron Collider (LHC), on the Swiss-French border, recreates Big Bang conditions to study fundamental particles.

About this subject

The Large Hadron Collider (LHC) is the world's largest and most powerful particle accelerator, located at CERN on the Swiss-French border. In its 27-kilometer circular tunnel, protons are accelerated to near-light speeds and collided head-on, generating temperatures billions of times hotter than the center of the Sun. These collisions recreate conditions that existed fractions of a second after the Big Bang, enabling scientists to study the nature of matter and the fundamental forces of the universe.

The LHC began operations in 2008 and in 2012 was crucial for the discovery of the Higgs boson, the particle that gives mass to other particles. This discovery earned François Englert and Peter Higgs the Nobel Prize in Physics in 2013. Beyond the Higgs, the LHC seeks to understand dark matter, the matter-antimatter asymmetry, and other open questions in particle physics.

The LHC tunnel lies at an average depth of 100 meters, traversing limestone and sedimentary rock. Along the ring, four major detectors (ATLAS, CMS, ALICE, and LHCb) analyze the debris from collisions. CERN, founded in 1954, includes more than 20 member states and exemplifies international scientific cooperation.
