A Small Glimmer of Hope For Faster-Than-Light Neutrinos

sciencehabit writes "The CERN particle physics laboratory in Geneva has confirmed Wednesday's report that a loose fiber-optic cable may be behind measurements that seemed to show neutrinos outpacing the speed of light. But the lab also says another glitch could have caused the experiment to underestimate the particles' speed. The other effect concerns an oscillator that gives its readings time stamps synchronized to GPS signals. Researchers think correcting for an error in this device would actually increase the anomaly in neutrino velocity, making the particles even speedier than the earlier measurements seemed to show."

    The fault is not with CERN but the press coverage. The claims out of CERN was an effect they could not explain, and that was the literal truth. Now they are getting deeper into it and finding flaws, which is not a surprise when working this close to what is possible with current technology. Before they can reliably say either way, they will need to do a lot more experiments and have independent verification. The scientists never claimed otherwise. Who you should stop taking seriously is journalists writing nonsense about things they do not understand.

    Thats exactly what they did.

    They released their results and said "we didn't quite yet figure out if there is a problem with our stuff, but here, maybe you guys can find something".

    They didn't come out day one and shouted "we have FTL nutrinos, fuck all you bitches in chemisty".

  3. It's not CERN by Anonymous Coward · · Score: 5, Informative

    The original article is way, way misleading. It makes it sound like the people in CERN are to blame. However, CERN is just the source of the neutrinos. The detectors in the other end is the Gran Sasso lab in Italy. The whole shebang is called the OPERA experiment.

    Now, the problem(s) were found in the Gran Sasso side. For a slightly more accurate reporting, see http://profmattstrassler.com/2012/02/24/finally-an-opera-plot-that-makes-some-sense/, especially the first comment.
