In the last quarter of 2011, Gran Sasso National Laboratory published a paper suggesting that neutrinos may be travelling 60 nanoseconds faster than the speed of light; the published paper was an invitation for other physicists to scrutinise their data. Earlier this week, 16th March 2012, Scientific American reported on CERN’s ICARUS experiment, who recently announced that their measurements showed neutrinos “travelling at a velocity indistinguishable from the speed of light” and not 60 nanoseconds faster.
For further information, please read John Matson’s article published in Scientific American, “Not So Fast: Independent Measurement Shows Neutrinos Don’t Exceed Speed Of Light“. Alternatively ICARUS findings on the 60 nanosecond measurement problem can be found at arXiv.org. The evidence is beginning to confirm that Einstein’s Special Relativity stands fast and the current laws of physics as we understand them, are still factually accurate.
According to the current Standard Model of Particle Physics, Neutrinos are members of the Fermion-Lepton family, are electrically neutral and have a small amount of mass. They are not seen to be ‘massless’ like their Force carrier family of particles called Bosons, of which the photon (electromagnetic, or commonly known as ‘light’ carrier) is a member.
