Colliders are large scientific instruments designed to accelerate particles, such as protons or electrons, to high speeds and smash them together. This process allows scientists to study the fundamental components of matter and the forces that govern their interactions. One of the most famous colliders is the Large Hadron Collider (LHC), located at CERN in Switzerland. By analyzing the results of these high-energy collisions, researchers can discover new particles and test theories in particle physics. Colliders help answer important questions about the universe, including the nature of dark matter and the origins of mass, contributing to our understanding of the Standard Model of particle physics.
