The miracle did not happen: Neutrinos do not overcome the speed of light


In September 2011, a scientific sensation spread all over the world, which was not deprived of attention on Habré (see, for example, this and this topic). During the experiment conducted in the framework of the OPERA project at CERN , the scientists registered the neutrino beam speeding up the light - albeit quite a bit (the beam was only 60 nanoseconds ahead of the light), but the fact shook the minds of scientists and just science lovers from around the world. “Most of us have a feeling of being wrong, it just can't be real!” Said CERN spokesman James Gillis, but many secretly hoped for a miracle. Alas - a miracle, apparently, is canceled.

On February 23, 2012, the same Gillis made a statement in which he said that the previous results were most likely erroneous. During the rechecking of the experimental conditions, two factors were found that could introduce sufficient error in the results of observations. The first factor relates to the operation of the Vectron OC-050 oscillator, used for timing in the intervals between the synchronization signals that come from GPS , and the second is related to the quality of the connection of the fiber optic cable that supplies the external GPS signal. Gillis did not provide additional details, confining himself to the remark that new circumstances are enough to consider the sensational results of the experiment unreliable and to conduct repeated measurements.

And I wanted to believe in a miracle ...
