Once again, Einstein was right! As the researchers at CERN (European Centre for Nuclear Research) through their four experiments prove again that neutrinos do not travel faster than the speed of light. The four, Borexino, ICARUS, LVD and OPERA all measure a neutrino time of flight consistent with the speed of light. The result was presented by CERN Research Director Sergio Bertolucci at the 25th International Conference on Neutrino Physics and Astrophysics in Kyoto on June 8, 2012.
September 2011 ago, a team of researchers led by Dario Autiero, a CNRS researcher, as part of the OPERA international experiment, make a startling conclusion that neutrinos exceed the speed of light. The unexpected result come from the observation of a neutrino beam produced by the CERN accelerators in Geneva and detected 730 km further from the underground laboratory of Gran Sasso, in Italy.
As we know, in 1905, Einstein described in his theory of special relativity that the velocity of light as the maximum speed in the cosmos. This theory has become a cornerstone of modern physics, if the theory was wrong, that’s all mean the entire foundations of modern physics might have to be revised!
Considering the huge impact that such result could have on physics, as physicist Michio Kaku has said, every textbook would have to be rewritten, every experiment recalibrated. Cosmology, the very way we think of space, would be forever altered. The distance to the stars and galaxies and the age of the universe (13.7 billion years) would be thrown in doubt. Even the expanding universe theory, the Big Bang theory, and black holes would have to be re-examined.
Moreover, everything we think we understand about nuclear physics would need to be reassessed. Every school kid knows Einstein’s famous equation E=MC2, where a small amount of mass M can create a vast amount of energy E, because the speed of light C squared is such a huge number. But if C is off, it means that all nuclear physics has to be recalibrated. Nuclear weapons, nuclear medicine and radioactive dating would be affected because all nuclear reactions are based on Einstein’s relation between matter and energy.
As Carl Sagan once said, remarkable claims require remarkable proof, some experiments have been conducted by another researcher teams to prove the truth of the OPERA team result. One of them was the ICARUS team. In March 2012, the ICARUS experiment at the Italian Gran Sasso laboratory has reported a new measurement of the time of flight of neutrinos from CERN to Gran Sasso. The ICARUS measurement indicates that the neutrinos do not exceed the speed of light on their journey between the two laboratories.
Now, we can sure that Einstein was right and have been proven right, again!
