The ICARUS results evidence that neutrino moves at speed, not faster/slower, but same as c. The CERN results seem to be wrong due to some error in the equipment. http://arxiv.org/ftp/arxiv/papers/1203/1203.3433.pdf [Broken] aren't the neutrinos expected to travel slightly slower than c? (due to slight mass) or is the mass (velocity) difference too small to be noticeable, by any experiment? c = speed of light/photon the photon has zero rest mass. i am assuming that the relativistic mass of the photon is less than that of neutrino.
