A Matter Mystery: Neutrinos

Why does matter exist? It may seem like a strange question, but according to current models of the early universe, matter shouldn’t exist. In physics, the discrepancy between what we see—a universe filled with galaxies and a planet teeming with life—and what models predict we should see—absolutely nothing—is called the “matter-antimatter asymmetry problem.” 

During this science talk, Brian Malow and physicist Ryan Patterson will discuss this conundrum—which has dogged physicists for nearly a century—and the wispy particle called a neutrino—which might solve the problem once and for all.
