Amidst uproar and doubt over their experiment showing neutrino beams traveling faster than light, the scientists who said they achieved the stunning feat are repeating the measurement to prove they are correct.

Antonio Ereditato, the coordinator of the OPERA experiment, told the Associated Press they are continuing their studies because they wanted a confirmation of the results of the original experiment conducted by international team of scientists led by Dr. Sergio Bertolucci.

OPERA is a facility in Gran Sasso, Italy, that detected the faster-than-light neutrinos released 732 kilometres away by the CERN particle accelerator in Switzerland six months before the scientists announced the result on Sept. 23.

The particles traveled through air, water and rock arriving in Gran Sasso sooner than 24 thousandths of a second, which is the time it takes light to travel the same distance. But traveling 64 nanoseconds faster than light is impossible under Albert Einstein's Theory of Special Relativity, which says that nothing is faster than light.

The scientific community was not convinced. Moreover, other scientists disputed the results of the experiment.

"The criticism is that the results we had were a statistical quirk. The test should help address this," Stavros Katsanevas, deputy head of France's National Institute for Nuclear Physics and Particle Physics said, according to AFP.

Katsanevas revealed that they have started the new test using a special form of proton beam at CERN to assess a modified measurement technique.

Katsanevas is the co-author of the design of the neutrino beam from CERN to Gran Sasso.
