Graduate students of the Institute for Particle Physics Phenomenology (Durham University) were substituting for Sir Peter Higgs. They asked their audience a question with no clear answer yet positions them to discuss the Higgs Boson. They all appear to be listening. Perhaps a person in the audience is giving their best shot at an answer. We will try to get some feedback from those students to learn about this moment in time and about their understanding of the Higgs Boson and an answer to their question.
