Scientists break speed of light

Scientists have finally exceeded the speed of light, causing a light pulse to travel hundreds of times faster than normal.

It raced so fast the pulse exited a specially-prepared chamber before it even finished entering it.

The experiment is the first-ever evidence of faster-than-light motion.

The result appears to be at odds with one of the basic principles of Albert Einstein's theory of relativity, that nothing can go faster than the speed of light in a vacuum, about 186,000 miles per second.

However, Lijun Wang, one of the scientists from the NEC Research Institute in Princeton, N.J., says their findings are not at odds with Einstein.

She says their experiment only disproves the general misconception that nothing can move faster than the speed of light.

The scientific statement "nothing with mass can travel faster than the speed of light" is an entirely different belief, one that has yet to be proven wrong. The NEC experiment caused a pulse of light, a group of waves with no mass, to go faster than light.

The key to the experiment was that the pulse reformed before it could have gotten there by simply travelling through empty space. This means that, when the waves of the light distorted, the pulse traveled forward in time.

The NEC researchers published their results in this week's issue of the journal Nature.
