Source sentences:
text: According to the theory of special relativity, the question of neutrino velocity is closely related to their mass: If neutrinos are massless, they must travel at the speed of light, and if they have mass they cannot reach the speed of light.
text: If neutrinos are massless, then they move at the speed of light and we can't go faster than the particle to switch the helicity.
text: The neutrino is an elementary particle that holds no electrical charge, travels at nearly the speed of light, and passes through ordinary matter with virtually no interaction.
