> ScienceNeutrinos are cosmic particles that are highly volatile with the ability to pass through matter without undergoing any change. They act like electrons under nuclear forces but have no charge and are thought to have almost negligible mass. As neutrinos are present throughout the universe, to be able to describe the universe, we must describe the neutrinos. Researchers said that it might be massless too, as the number is an upper limit not a lower limit. Researchers said that with time as physics and engineering improve we might be able to get a definitive result.
