IS TIME TRAVEL POSSIBLE ? –ARE NEUTRINOS FASTER THEN LIGHT?

OPERA experiment reports anomaly in flight time of neutrinos from CERN to Gran Sasso

Following the OPERA collaboration’s presentation at CERN on 23 September, inviting scrutiny of their neutrino time-of-flight measurement from the broader particle physics community, the collaboration has rechecked many aspects of its analysis and taken into account valuable suggestions from a wide range of sources. One key test was to repeat the measurement with very short beam pulses from CERN. This allowed the extraction time of the protons, that ultimately lead to the neutrino beam, to be measured more precisely.
