Many observations tell us that we need new physics beyond the Standard Model. However, there is very little guidance on where to go: the Standard Model fits experiment remarkably well and is mathematically consistent. Fortunately, there is a light at the end of the tunnel in the form of neutrino oscillations and masses. In this video, we will talk about what neutrinos really are, how they communicate with other particles, why they are massless in the Standard Model, and how we know they actually have mass.
