"A team of researchers from the Ecole Polytechnique Fédérale de Lausanne (EPFL) has successfully demonstrated, for the first time, that it is possible to control the speed of light – both slowing it down and speeding it up – in an optical fiber, using off-the-shelf instrumentation in normal environmental conditions. Their results, to be published in the August 22 issue of Applied Physics Letters, could have implications that range from optical computing to the fiber-optic telecommunications industry.
This actually challenges the Theory of Relativity. Another proof that our knowledge of physics is far from complete, and that there still is the possibillity of finding out more.. Quite a few theories, espescially in the fields of astro-physics and quantum-mechanics are heavily based on the fact that the speed of light is an absolute constant....
