New light speed experiment confirms earlier result

[Archean]

The team which found that neutrinos may travel faster than light has carried out an improved version of their experiment - and confirmed the result. If confirmed by other experiments, the find could undermine one of the basic principles of modern physics.

Critics of the first report in September had said that the long bunches of neutrinos (tiny particles) used could introduce an error into the test. The new work used much shorter bunches.
