On Friday, a news story came out that a second experiment seems to support the results of an earlier experiment which showed neutrinos might be moving faster than light. I commented about this on Google+ at the time, but I want to post about it here as well. Let me be clear: this new result does not confirm FTL neutrinos! What it did was essentially eliminate one possible source of error. A big one still remains.
Let me recap: In September, a team of scientists
at CERN working with the OPERA detector in Italy found that beams of neutrinos — subatomic particles that can travel straight through matter — seemed to get from the source in Geneva to the target in Italy 60 nanoseconds faster than a beam of light would make the trip. If true, it means they were moving faster than light (what scifi geeks like me call FTL) which, according to all the physics we understand, is impossible.
