Light Speed Barrier Broken ?- Science and Scence Fiction Communities Reel.

Even physical laws are made to be broken, or so new insights into physics seem to imply.

'We have broken speed of light' - Telegraph: "'We have broken speed of light' By Nic Fleming, Science Correspondent Last Updated: 12:01am BST 16/08/2007 A pair of German physicists claim to have broken the speed of light - an achievement that would undermine our entire understanding of space and time."

In a related bit of disturbing news - for science and science fiction alike - there comes the revelation that the speed of light itself may vary.

It came as a shock, then, for astronomer John Webb, of the University of New South Wales in Sydney, when he discovered that light could be fickle. Webb analysed light from super-bright quasars and found that 12 billion years ago, the fine-structure constant or alpha - an amalgamation of constants, including the speed of light - seemed in fact to be inconstant, being lower long ago. "I was surprised and had expected a null result," says Webb.
