Browsing: Neutrinos
Neutrinos are elusive, nearly massless subatomic particles that play a fundamental role in the universe, despite their weak interactions with matter. Produced in vast quantities by nuclear reactions in stars, supernovae, and even during radioactive decay on Earth, neutrinos rarely interact with other particles, making them extremely difficult to detect. There are three known types—electron, muon, and tau neutrinos—and they can oscillate between these forms as they travel through space. Studying neutrinos helps scientists probe the inner workings of stars, understand the nature of fundamental forces, and investigate unsolved mysteries in particle physics and cosmology, including the origin of mass and the asymmetry between matter and antimatter.
