Speed Of Light Still Faster Than Neutrinos [Confirmed]

CERN Neutrino Speed Test

Physicists at the CERN laboratory have an announcement, neutrinos are not in fact faster than the speed of light. The group confirmed that faulty equipment led to that very claim in 2011 in what at the time was called a “groundbreaking” study.

The neutrino claim was made in September 2011 by a team of particle physicists who detected the increased speed as the neutrino’s traveled from CERN to the Gran Sasso lab. At the time researchers says they beat the universal speed limit by 60 nanoseconds.

Following the speed record scientists conducted the same study 15,000 times with the same results.

If the 2011 tests were correct it could have overturned Einstein’s special theory of relatively which claims that nothing can move faster than the speed of light.

The new results were announced at the International Conference on Neutrino Physics and Astrophysics in Kyoto on June 8 by CERN research director Sergio Bertolucci.

New tests surrounded four experiments which all found that neutrino’s do in fact travel below the speed of light.

According to CERN the original study was “attributed to a faulty element of the experiment’s fibreoptic timing system.”

In March 2012 Opera experiment spokesperson Antonio Ereditato resigned from his post following the unaccounted-for error that led to Icarus’ own tests featuring neutrino’s.
