The Italian researchers that the travel time of neutrinos measured, for the second time to the conclusion that the particles faster than the speed of light must have traveled. Within the research team is, however, still division.
The experiment is a repetition of the measurements, which last september the results were published. The conclusion that the Italians went, that the neutrinos – almost massaloze elementary particles – their way just a bit faster than light would have traveled, did a lot of dust raised. Breaking the speed of light flies, after all, against natuurkundewetten, who argue that there is infinite amounts of energy would be required. Nevertheless, was the experiment after the publication in september by the Italians repeated, after which they reached the same conclusion.
The experiment involves sending neutrino beams from the CERN research institute in Switzerland, to a detector 730 km away in a mine in the Italian village of Gran Sasso. The first results of this so-called Opera experiment, based on 16,000 readings listed, where the neutrinos roughly 60 nanoseconds sooner arrival than when they are with the speed of light would travel.
In the repetition of the experiment, in which a much smaller number of observations, only twenty pieces, were done, the result was confirmed. One of the Opera staff, Luca Stanco, states that the quality and intensity of the measurements and this time was higher than before. During the second experiment was not only the faster-than-light-measurement is again confirmed, the previously determined measurement error of 10 nanosecond was confirmed.
Stanco wanted not to have his name under the first publication, but it is there now, with the new results that the measurements would confirm, however, willing. Nevertheless, it wants almost half of the vijftienkoppige research team, seven man, that as yet do not. A conclusive evidence that the neutrinos actually exceed the light speed is not yet delivered, as long as the experiment by other scientists can be repeated. The planned experiment of the Italians with a second detector in Gran Sasso would possibly still be a measurement error can contain, if that is the cause of the results from the first two measurements.
