A neutrino (denoted by the Greek letter ν) is a fermion (an elementary particle with spin of
1
/
2
) that interacts only via the weak interaction and gravity.[2][3] 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.[1] The weak force has a very short range, the gravitational interaction is extremely weak, and neutrinos do not participate in the strong interaction.[4] Thus, neutrinos typically pass through normal matter unimpeded and undetected.


“ I don’t understand neutrinos are everywhere. They pass through us all the time. They are harmless. Harmless to us but not achaian tech. Molecules knocked out of atoms, protons ripped apart. With enough concentrated force, water can cut through steel. “-Another life
