In 1930, phycisist Wolfgang Pauli suggested the existence of the neutrino particle to compensate the unexplained energy loss in particle collisions and in beta decays. The energy could not have disappeared due to the Law of the Conservation of Energy; but there was a small but flagrant amount of energy that was gone. Since the energy it contained was almost 0, the particle would have to have little to no mass, so it would be exceedingly difficult to detect. But now, after finally observing it (if only by bits) it is known as the neutrino particle (subtypes- electron neutrino, muon neutrino, and tau neutrino). After declaring its existence, Pauli stated: "I have done a terrible thing. I have postulated the existence of a particle that cannot be detected."
