Peter Higgs, (born 29 May 1929) is a British theoretical physicist and emeritus professor at the University of Edinburgh. He is best known for his 1960s proposal of broken symmetry in electroweak theory, explaining the origin of mass of particles. This so-called Higgs mechanism predicts the existence of a new particle the Higgs boson. CERN announced on July 4th, 2012 that they had experimentally established the existence of a Higgs-like boson.
The Nobel Prize in Physics 2013 was awarded jointly to François Englert and Peter W. Higgs "for the theoretical discovery of a mechanism that contributes to our understanding of the origin of mass of subatomic particles, and which recently was confirmed through the discovery of the predicted fundamental particle, by the ATLAS and CMS experiments at CERN's Large Hadron Collider" (click for more)
"Prof Tejinder Jim Virdee, Imperial College London, developed new technologies within the detector that ultimately allowed it to find the Higgs - the mechanism which explains how sub-atomic particles came to have substance, or mass."
Peter Higgs CH FRS FRSE theoretical physicist, Nobel Prize laureate and emeritus professor. Best known for his theory, explaining the origin of mass of elementary particles in general and of the W and Z bosons in particular. This so-called Higgs mechanism, which was proposed by several physicists besides Higgs at about the same time, predicts the existence of a new particle, the Higgs boson (which was often described as "the most sought-after particle in modern physics
Einstein proved that gravity does not exist, i.e. that spacetime is warped by mass. String theory proposes a new particle called the "graviton" which transmits the force of gravity. The debate rages on.
