Caltech physicist Barry Barish is the director of the global design effort for the International Linear Collider, which is currently in the planning stages. If built, the ILC would smash together electrons and their antimatter counterparts, positrons, at nearly the speed of light. The ILC would complement the Large Hadron Collider, a European proton collider that is the world’s most powerful but has had technical problems that will prevent it from operating at full power until 2013. That gives the world’s second most powerful collider, the Tevatron at the Fermi National Accelerator Laboratory in Batavia, Ill., a slim chance to be first to find evidence for the long-sought Higgs boson, which has been proposed as the particle responsible for providing other particles with mass. Following a presentation on February 22 in San Diego at the American Association for the Advancement of Science’s annual meeting, Barish answered questions from the audience and news medi
