Neutrinos

A neutrino ( ; denoted by the Greek letter Nu (letter)|) is an elementary particle that interacts via the weak interaction and gravity. The neutrino is so named because it is electrically neutral and because its rest mass is so small (-ino) that it was long thought to be zero. The rest mass of the neutrino is much smaller than that of the other known elementary particles (excluding massless particles).

Neutrinos, the lightest of the known subatomic particles, lack measurable electromagnetic properties and interact only via the weak nuclear force (when ignoring gravity). Matter is virtually transparent to neutrinos and c
