Source sentences:
text: From their very conception, neutrinos were assumed by scientists to be massless.
text: In 1975, after the success of the two-component theory, there was still a general belief that neutrinos are massless particles.
text: The neutrinos are explicitly assumed to be massless.
text: according to the standard model, neutrinos should be massless.
text: As it is well known according to the two-component neutrino theory [23–25], the neutrino is massless and for one neutrino type only a left-handed neutrino and a right-handed antineutrino exist.
text: predicts that neutrinos should be massless.
text: First of all, neutrinos are no longer believed to be massless, although they are tiny, the masses are likely in the sub-eV region.
text: Why did everyone think the neutrino was massless?
text: If neutrinos are massless then it makes sense that they can all be left-handed, and anitneutrinos can be right-handed.
