Apparently, a team of scientists working at CERN have found evidence suggesting that neutrinos can travel faster than the speed of light. While this has turned a few heads, the wide consensus is that this will probably turn out to be some kind of systematic error and not a real effect. Extraordinary claims require extraordinary evidence, and this evidence has to pass a hell of a lot more tests — and be reproduced by a lot more people — before anyone, including the team who produced the results, will feel comfortable saying that they’ve found a way around the ultimate speed limit. But why would this be such an extraordinary claim? The speed of light is a hard limit in Einstein’s relativity, but why?…Read more "Neutrinos and Flux Capacitors"
