=== Neutrinos ===
In 1985, Chodos proposed that [[neutrino]]s can have a tachyonic nature.<ref name="Chodos" /> The possibility of standard model particles moving at faster-than-light speeds can be modeled using [[Lorentz invariance]] violating terms, for example in the [[Standard-Model Extension]].<ref name="Colladay" /><ref>
