Higgs boson
Peter Higgs was the first person to think of it, and the particle was found in March 2013. It is part of the Standard Model in physics, which means it is found everywhere. It is one of the 17 particles in the Standard Model. The Higgs particle is a boson. Bosons are particles responsible for all physical forces except gravity. Other bosons are the photon, the W and Z bosons, and the gluon. Scientists do not yet know how to combine gravity with the Standard Model.
