Why Do Neutrinos Have Mass? A Small Question with Huge Consequences

The video explores the enigmatic nature of neutrinos, tiny particles that are difficult to detect and understand. It delves into their flavors, mass, and the challenges in measuring them. The seesaw mechanism is introduced as a potential explanation for their mass, suggesting a connection between light left-handed and heavy right-handed neutrinos. The video also discusses the role of neutrinos in the universe's evolution and their potential to unlock new physics beyond the Standard Model. Despite the mysteries, progress is being made, with recent experiments hinting at differences between neutrinos and antineutrinos.
