Large Hadron Collider

The Large Hadron Collider (LHC) is the world’s largest and most powerful particle accelerator, located at CERN. It is designed to test predictions of high-energy physics, particularly the Standard Model, by colliding protons or heavy ions at near-light speeds.

Key Scientific Achievements

Higgs Boson Discovery: Confirmed the existence of the Higgs boson, validating the mechanism by which elementary particles acquire mass.
Mass from Energy: Demonstrates the inverse process of nuclear fission/fusion, where kinetic energy is converted into new mass ( $E = m c^{2}$ ), creating heavy particles from high-energy collisions.
Quark-Gluon Plasma: Recreated conditions similar to those just after the Big Bang, allowing study of the state of matter that existed microseconds after the universe’s birth.

Detailed exploration of the LHC’s role in creating mass from energy and the discovery of the Higgs boson is available in CERN’s LHC: Creating Mass from Energy and Discovering the Higgs Boson.
The video “CERN Built the Opposite of an Atomic Bomb” by The Action Lab provides a conceptual overview of these processes [CERN’s LHC: Creating Mass from Energy and Discovering the Higgs Boson].
