Answer
The Brout-Englert-Higgs mechanism is a theory in physics that explains how particles get mass. It was proposed by Francois Englert, Robert Brout, and Peter Higgs in 1964. The mechanism states that the Higgs field, which is a field that permeates all of space, gives mass to particles that interact with it. This mechanism has been experimentally confirmed by the discovery of the Higgs boson in 2012.
