Light Stopped, Held And Re-emitted By A Crystal

Posted by timothy on from the dark-crystal dept.

nherc writes: "An article in Nature talks about an incredible new crystal that can actual stop and hold light to be later emitted. It's mentioned light has previously been "slowed" by super cooled gases, but this certainly blows that away. They mention this could be a major step towards quantum computing."

  1. Magical Crystal = Glow In The Dark Stuff? by citizenc · · Score: 2, Redundant

    Uerm.. correct me if I'm wrong, but doesn't glow-in-the-dark stuff "stop and hold light to be later emitted"?

    So what? The Elves have been doing this for ages. Just ask Galadriel.

    O Elbereth! Gilthoniel!

    OK, so I've been reading LOTR too much again...

    Cheers,

  3. Short story about slow glass by Captain_Chaos · · Score: 0, Redundant

    I read a short SF story a long time ago which was about 'slow glass', which was ordinary glass except that light would take several decades to go through a piece as thick as a window pane. People made their living by 'farming' this glass; putting sheets of it on mountain slopes and other places with great views, so people could later buy these sheets and put them in their homes for a decade of looking out on a mountain vista despite living in a crowded city. Interesting things happened such as murders being witnessed that took places years before.

    Does anyone remember this? I can't find the story anymore and I have no idea who wrote it or where it was published.
