neutrino is a fundamental, electrically neutral subatomic particle with a very small mass that interacts only through the weak nuclear force and gravity, allowing it to pass through most matter unimpeded. Produced in nuclear reactions like those in the sun, supernovae, and nuclear reactors, there are three types (electron, muon, and tau) that can change between flavors as they travel, a phenomenon called neutrino oscillation. Trillions pass through the Earth every second, making them abundant but difficult to detect, requiring massive underground or underwater
