Neutrinos: the chaotic gremlins of particle physics! First they're massless, then they have mass, then they're breaking cosmic speed limits, then—oops, just kidding! But wait, now they have NEGATIVE mass? And IMAGINARY mass?? These ghostly little particles are basically the teenagers of the Standard Model—refusing to follow rules and constantly changing their identity. Physicists worldwide are tearing their hair out while neutrinos are somewhere in the universe giggling at our confusion. The ultimate cosmic pranksters!
