Scientists say they have found hints of the existence of the Higgs Boson, anever before seen subatomic particle long thought to be a fundamental building block of the Universe.
The standard Model of particle physics lays out the basic of how elementary particles interact in the universe. But the theory crucially fails to explain how particles actually get their mass.
Particles, or bits of matter, range in size and can be larger or smaler than atoms. Electrons, protons and neutrons, for instance are the subatomic particles that make up an atom.
Scientists belive that the Higgs Boson is the particle that gives all matter its mass.
