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 ...
