Our nation’s official keepers of time and other standards are breaking one of the cardinal rules: They have figured out how to make superluminal light pulses. This paradoxical sentence — faster-than-light light — is from a new paper explaining how to make the sine wave of light hunch in on itself and arrive a few nanoseconds earlier than it would if it had moved at light speed.
Another new twist in the science of scofflaw neutrinos: A second Italian physics group now says they are not moving faster than light after all. So the foundations of modern physics appear safe for now — but this debate will likely not be settled for some time.
Remember in September when neutrinos were observed moving faster than the speed of light, potentially overturning everything we thought we knew about physics? It was met with all sorts of skepticism and dubiety, so the physicists decided to replicate their experiment and take new measurements.
Well, the new results are in, and they confirm the original findings.
