This is the live Webcast from CERN on Friday September 23, 2011. Given the potential far-reaching consequences of the OPERA experiment --- which observes a neutrino beam from CERN 730 km away at Italy's INFN Gran Sasso Laboratory, indicating that the neutrinos travel at a velocity 20 parts per million above the speed of light --- independent measurements are needed before the effect can either be refuted or firmly established, according to a CERN statement just issued. The OPERA collaboration has therefore decided to open the result to broader scrutiny.
