The document discusses the Higgs boson particle, also known as the "God particle". It describes how the particle was theorized in 1964 by Peter Higgs and others to help explain how elementary particles acquire mass. Researchers at CERN used the Large Hadron Collider to finally detect the Higgs boson in 2012 through high-energy collisions of protons, confirming its existence after decades of experiments. The discovery of the Higgs boson was a major achievement that validated the Standard Model of particle physics.
