According to Einstein's theory of special relativity, nothing can go faster than the speed of light, but Einstein didn't know about neutrinos. In fact, physicists are just beginning to be able to study these tiny particles that zip through rock, flesh, and space faster than the speed of light... or do they? In the true nature of science, those who clocked the neutrinos at a speed nobody imagined possible are inviting other scientists to replicate the experiment to try to prove or disprove their results.
