Bad wiring could be behind superluminal neutrino result

FEB 22, 2012

Science : A bad connection between a GPS unit and a computer could be behind the OPERA collaboration’s determination last year that neutrinos travel faster than light. Sources familiar with the experiment told Science‘s Edwin Cartlidge that they had discovered a loose connection between a computer and a fiber optic cable that connects to the GPS receiver used to correct the timing of the neutrinos’ journey. The original timing discrepancy was 60 nanoseconds. After tightening the connection, the researchers found that data arrive 60 ns earlier than they had previously assumed, thereby nullifying the discrepancy and removing the need to invoke superluminal travel.
