The Large Hadron Collider
Deep beneath rolling hills on the outskirts of Geneva lies the 27km ring of superconducting magnets powering the world’s largest and most powerful particle accelerator, the Large Hadron Collider (LHC) at CERN. Since 2010, physicists have been firing subatomic particles around the collider, crashing them into each other to learn more about their composition and behaviour. CERN was founded in the wake of World War II as a way to unite Europe’s scientific community, and the LHC is now run by scientists from more than 100 countries. Despite technical setbacks during construction, the LHC has already reshaped our understanding of particle physics, having confirmed the existence of the Higgs boson.
