The search for the origin of mass

We do not know what gives mass to elementary particles. However, I will explain why after years of experimental and theoretical research we have extreme confidence that the Large Hadron Collider at CERN will tell us. The most famous and simplest idea to generate mass is a single Higgs boson. I will present the case for and against the single Higgs boson theory, and argue why revolutionary understanding and discoveries are likely under any eventuality.
