Asunto: New neutrino news says not faster than light
| A different experiment measuring the time of flight of neutrinos between CERN in Geneva and Gran Sasso in Italy has published new results that indicate that neutrinos do not travel faster than light. In September 2011, unexpected results from the OPERA collaboration suggested that neutrinos travelling between the two laboratories were defying a key assumption that underpins modern physics – that nothing can travel faster than the speed of light. This caused an international media sensation and opened up the process of scientific scrutiny to the general public. Since then, physicists around the world have been rigorously checking the OPERA results, repeating and replicating experiments in an effort to establish whether the OPERA results are correct. But now the ICARUS experiment, which is also based at Gran Sasso, has reported results which indicate that neutrinos do not travel faster than the speed of light. The experiment has independent timing from the OPERA experiment, pointing to the possibility that there is a timing discrepancy on OPERA.STFC manages the UK subscription to CERN.
