Researchers in Switzerland have succeeded in breaking the cosmic speed limit by getting light to go faster than, well, light.
Or is it all an illusion?
Scientists have recently succeeded in doing all sorts of fancy things with light, including slowing it down and even stopping it all together. Now a team at the Ecole Polytechnique Fdrale de Lausanne (EPFL) in Switzerland is controlling the speed of light using simple off-the-shelf optical fibers, without the aid of special media such as cold gases or crystalline solids like in other experiments.
"This has the enormous advantage of being a simple, inexpensive procedure that works at any wavelength," said Luc Thvenaz, lead author of the study detailing the research.
