Physicist Costas Soukoulis and his research group at the U.S. Department of Energy?s Ames Laboratory on the Iowa State University campus are having the time of their lives making light travel backwards at negative speeds that appear faster than the speed of light. That, folks, is a mind-boggling 186,000 miles per second ? the speed at which electromagnetic waves can move in a vacuum. And making light seem to move faster than that and in reverse is what Soukoulis, who is also an ISU Distinguished Professor of Liberal Arts and Sciences, said is ?like rewriting electromagnetism.? He predicted, ?Snell?s law on the refraction of light is going to be different; a number of other laws will be different.?
