great achievement indeed

Boffins break the speed of light

Process doesn't break Einstein's theories

Iain Thomson, vnunet.com 06 Mar 2007

Scientists at
NEC have managed
to get a light beam to exceed the speed of light, something once thought to be
an unbreakable universal constant.

In the experiment a beam of light was passed through a specially prepared
caesium atomic chamber. The beam of light arrived at the far end 62 nanoseconds
sooner than would be expected under normal conditions.

"Our experiment is not at odds with
Einstein's
special relativity, but it does show that the generally held misconception that
nothing can move faster than the speed of light is wrong," the laboratory
reported.

"The statement only applies to objects with a rest mass. Light can be viewed
as waves and has no mass. Therefore, it is not limited by its speed inside a
vacuum."

The special chamber was cooled to as close possible to absolute zero
Combined with the caesium, this "rephased" the light waves
taking
them beyond 186,000 miles
