Britain’s Peter Higgs and Francois Englert of Belgium won the Nobel Prize for physics on Tuesday for predicting the existence of the Higgs boson particle that explains how elementary matter attained the mass to form stars and planets.

Half a century after their original work, the new building block of nature was finally detected in 2012 at the European Organization for Nuclear Research (CERN) centre’s giant, underground particle-smasher near Geneva.

The Higgs boson is the last piece of the Standard Model of physics that describes the fundamental make-up of the universe. Some commentators – though not scientists – have called it the “God particle”, for its role in turning the Big Bang into an ordered cosmos.

Higgs’ and Englert’s work shows how elementary particles inside atoms gain mass by interacting with an invisible field pervading all of space – and the more they interact, the heavier they become. The particle associated with the field is the Higgs boson.

Way to go, guys!
