Scientists Trap a Rainbow

An anonymous reader writes to tell us that Physicists from both the University of Surrey and Salford University have devised a method to trap a multi-colored rainbow of light inside a prism. "Previous attempts to slow and capture light have involved extremely low or cryogenic temperatures, have been extremely costly, and have only worked with one specific frequency of light at a time. The technique proposed by Professor Hess and Mr Kosmas Tsakmakidis involves the use of negative refractive index metamaterials along with the exploitation of the Goos Hänchen effect, which shows that when light hits an object or an interface between two media it does not immediately bounce back but seems to travel very slightly along that object, or in the case of metamaterials, travels very slightly backwards along the object."

    But there are a ton of virgin websites that would be just a sheer delight to troll.

    If you want virgins, go to Iraq, strap a bomb to yourself and walk towards the nearest US patrol. You'll get 72, apparently.

    Sorry, but you *were* trolling.
    Your linked post added nothing to the debate, it's only intent was to attack the parent poster.
    Even if you were right, it's still trolling.

    The funniest thing I found about the post you linked to was the sig from the guy you were trolling.

    "My Karma ran over your dogma."

    Indeed in this case, it looks like it did.
