Particle physicist Dr Brian Cox explains how quantum mechanics has changed the way we think the world works, and why it predicts the existence of a particle that's never been seen.
The Higgs boson is a mysterious particle that explains why things have mass. Cox reveals how the Large Hadron Collider experiment at CERN is intended to smash particles together so violently that the Higgs boson can be detected and studied for the first time.
