Neutrinos are nearly massless subatomic particles that are produced in nuclear reactions, like those in the sun and stars. While they travel exceedingly fast, neutrinos do not surpass the speed of light, which remains the universal speed limit according to Einstein’s special relativity. Neutrinos pass through ordinary matter with ease, making them difficult to detect without specialized instruments.
