The European organisation for nuclear research, Cern, last year claimed that Albert Einstein's theory of relativity was wrong. Now they claim that the theory of relatively was indeed right.

In September 2011, Cern had claimed that the sub-atomic particles which are known as neutrinos were travelling faster than the speed of light. They claimed that neutrinos arrived 60 nanoseconds earlier than light.

This theory actually shook the scientific world because Albert Einstein's theory of relativity clearly says that nothing in this universe can travel faster than light.

Now Cern says that due to some technical difficulties between the GPS unit and a computer had affected the reading and they found that neutrinos don't travel faster than light.

Cern's retraction was first published in the Science Insider journal.

"One has to realise that the collaboration has never stopped to try to 'kill' the measurement (proving that it was erroneous)," said Sergio Bertolucci, Director of Research at Cern told BBC News.
