Was Einstein wrong, or was cable loose?

GENEVA/CHICAGO - The world of science was upended last year when an experiment appeared to show one of Einstein's fundamental theories was wrong - but now the lab behind it says the result could have been caused by a loose cable.

Physicists at the CERN research institute near Geneva appeared to contradict Albert Einstein's 1905 Special Theory of Relativity last year when they reported that sub-atomic particles called neutrinos could travel fractions of a second faster than light.

Einstein's Special Theory of Relativity, which underpins the current view of how the universe works, says that nothing can travel faster than light, and doing so would be like traveling back in time.
