John neutrino

John neutrino, often referred to simply as a neutrino, is a tiny, nearly massless particle that travels through space at nearly the speed of light. It’s produced in various processes, such as nuclear reactions in the sun, radioactive decay, and cosmic events. Neutrinos are very difficult to detect because they rarely interact with matter, passing through planets and stars almost undisturbed. They are a key part of understanding the universe's fundamental workings, as they help scientists study processes that are otherwise invisible and answer questions about the origins of stars, galaxies, and our universe itself.
