    Invisibility

    I got this off of Yahoo this morning, all I got to say about it, wouldn't it be very cool!.

    LONDON (Rueters) - It's unlikely to occur by swallowing a pill or donning a special cloak, but invisibility could be possible in the not too distant future, according to research published on Monday.

    Harry Potter accomplished it with his magic cloak. H.G. Wells' Invisible Man swallowed a substance that made him transparent.

    But Dr Ulf Leonhardt, a theoretical physicist at St Andrews University in Scotland, believes the most plausible example is the Invisible Woman, one of the Marvel Comics superheroes in the "Fantastic Four."

    "She guides light around her using a force field in this cartoon. This is what could be done in practice," Leonhardt told Reuters in an interview. "That comes closest to what engineers will probably be able to do in the future."

    Invisibility is an optical illusion that the object or person is not there. Leonhardt uses the example of water circling around a stone. The water flows in, swirls around the stone and then leaves as if nothing was there.

    "If you replace the water with light then you would not see that there was something present because the light is guided around the person or object. You would see the light coming from the scenery behind as if there was nothing in front," he said.

    In the research published in the New Journal of Physics, Leonhardt described the physics of theoretical devices that could create invisibility. It is a follow-up paper to an earlier study published in the journal Science.

    "What the Invisible Woman does is curve space around herself to bend light. What these devices would do is to mimic that curved space," he said.

    Although the devices are still theoretical, Leonhardt said scientists are making advances in metamaterials -- artificial materials with unusual properties that could be used to make invisibility devices.

    "There are advances being made in metamaterials that mean the first devices will probably be used for bending radar waves or the electromagnetic waves used by mobile phones," he said.

    The devices could be used as protection mechanisms so the radiation emitted from mobile phones does not penetrate electronic equipment. It is guided around it.

    "It is very likely that the demonstration for radar would come first and very soon. To go into the visual will take some time but it is also not so far off," Leonhardt said.

    Wow sounds neat.
    When I read this I think of one of the conspiracy theories that I have read about, The Philadelphia Experiment. If I remember correctly they attempted to make a battle ship disappear using electric fields. The arguments about what happened after are rather strange and somewhat hard to swallow but the concept is similar.

        Nah, the Philidelphia Experiment was the US Government attempting the first steps in developing a prototype of Chronosphere technology...
        Jayne - Ain't logical. Cuttin' on his own face, rapin' and murdering - Hell, I'll kill a man in a fair fight... or if I think he's gonna start a fair fight, or if he bothers me, or if there's a woman, or if I'm gettin' paid - mostly only when I'm gettin' paid. But these Reavers... last ten years they show up like the bogeyman from stories. Eating people alive? Where's that get fun?
        Kaylee - Shepherd Book said they was men who just reached the edge of space, saw a vasty nothingness, and went bibbledy over it.
        Jayne - Oh, hell, i've been to the edge. Just looked like... more space.
