The Higgs boson is one of the particles that have been predicted, but has only recently been detected. It was predicted by several physicists, including theoretical physicist Peter Higgs. That is where the first part of the name came from.
OK, so what is a boson? That huge number of elementary particles is divided into two major groups: fermions and bosons. Fermions are sometimes called matter particles because they are the particles that take up space. Two fermions cannot be in the same spot at the same time.
