Are the particles travel faster than light? Not so fast

After a study in September, suggested that neutrinos can travel faster than light - a discovery that would shake Einstein's theory of relativity, a more recent study shows that the test results should have been a mistake.

The scientists included in the OPERA experiment, carried out in the Gran Sasso laboratory, near Rome, said some of the neutrinos from the CERN research center in Switzerland, traveled faster than the speed of light.

Now, a study called ICARUS in the Gran Sasso indicates that the energy levels of the neutrinos that reach very high. If neutrinos actually traveled faster than light, had lost most of its energy, says the ICARUS team.

"The difference between the speed of neutrinos and the speed of light can not be as great as that observed by OPERA, and is certainly smaller than three orders of magnitude, and is compatible with zero," said CERN physicist Tommaso Dorigo, ICARUS commenting on the results.

Another recent experiment at CERN confirmed the original findings of the experiment in September, but could have been prone to the same errors - if any - as the original experiment.

Independent experiments are being prepared in Italy, USA and Japan to try to replicate the results of operations. ADS HERE
