    "For generations, physicists believed there is nothing faster than light moving through a vacuum -- a speed of 186,000 miles per second. But in an experiment in Princeton, N.J., physicists sent a pulse of laser light through cesium vapor so quickly that
    it left the chamber before it had even finished entering. The pulse traveled 310 times the distance it would have covered if the chamber had contained a vacuum. Researchers say it is the most convincing demonstration yet that the speed of light --
    supposedly an ironclad rule of nature -- can be pushed beyond known boundaries, at least under certain laboratory circumstances. [...] The results of the work by Wang, Alexander Kuzmich and Arthur Dogariu were published in Thursday's issue of the journal
    Nature." http://www.cbsnews.com/news/faster-than-the-speed-of-light/

    Einsteinians explain why Einstein's relativity "seems to survive":

    "A pulse of light that passes through a transparent chamber filled with specially prepared cesium gas appears to be pushed to speeds of 300 times the normal speed of light. That is so fast that, under these peculiar circumstances, the main part of the
    pulse exits the chamber even before it enters. [...] But Einstein's theory, and at least a shred of common sense, seem to survive, the physicists explain, because the effect could never be used to signal back in time to change the past and, in the
    example, avert the accident." https://www.nytimes.com/2000/05/30/science/faster-than-light-maybe-but-not-back-to-the-future.html
