In 1993, Noble prize-winning physicist, Leon Lederman, published a book entitled, The God Particle. The book was about a particle, hypothesized most prominently by Peter Higgs, which is associated with a field that permeates the universe and gives mass to the elementary particles in the Standard Model of particle physics. On July 4, 2012, physicists working at the Large Hadron Collider in Europe, the world’s largest particle accelerator, announced they had discovered signs of a new particle that looks an “awful lot like the long sought after” Higgs particle. So does this mean that the secret to the universe has now been revealed and that with the God particle in its sights, there is nothing left for particle physics to discover? Or does this discovery simply convert the mystery of particle mass into the mystery of the properties of the Higgs field? Learn what the Higgs particle really is and what the recent discovery really means in this episode, where host Philip Mereton talks with John Gunion, Distinguished Professor of Physics at the University of California at Davis, and co-author of the The Higgs Hunter’s Guide.
