How do neutrinos work?
assistant
Neutrinos are elementary particles with very little mass and no electric charge. They interact very weakly with matter, making them extremely difficult to detect. Neutrinos are produced naturally in the Sun through nuclear reactions, and they travel to Earth at close to the speed of light. On Earth, neutrinos can interact with other particles and thus can be studied through the collisions they produce. The mass of neutrinos is very small, so the only way to determine them is to measure their energy, momentum, and spin. By studying neutrinos, scientists can learn more about the fundamental properties of matter and energy.
