CERN Experiments

Definition

CERN experiments refer to a series of scientific investigations conducted at the European Organization for Nuclear Research (CERN), focused on exploring the fundamental aspects of particle physics. These experiments aim to understand the fundamental building blocks of matter, the forces that govern their interactions, and phenomena like nuclear fission and fusion. They involve advanced technology and massive particle accelerators, like the Large Hadron Collider (LHC), which collide particles at high energies to create conditions similar to those just after the Big Bang.
