AMAZING PHOTO! scientists closer to creating invisibility cloak

http://www.cnn.com/2008/TECH/science....ap/index.html

WOW that photo really is amazing. And it's 5 years old. Who knows how close they are now.

It must be working. I don't even see a picture on that page!

I just read an article that seems to be about the same story: http://nextbigfuture.com/

And it has what I think is the picture you are looking for above.

Re: AMAZING PHOTO! scientists closer to creating invisibility cloak

I wonder if they would've ever thought to try if Star Trek hadn't had the idea first. Does the idea of concealing something by bending light around it appear in SF lit prior to TOS?

Re: AMAZING PHOTO! scientists closer to creating invisibility cloak

Well, the idea of invisibility in science fiction goes all the way back to H.G. Wells' The Invisible Man, but it's been a while since I've read it, so I can't remember the mechanism of invisibility right now.

And then there's always Sue Storm. Both predate Trek.

I always thought Trek cloaks worked via radiation, sending an object out of phase. Though I'm not sure how TOS cloaks worked (or if they even tried to explain them). The earliest light-bending cloak I can remember is in Predator, although I'm sure there were examples before that.

In RL metamaterials are a product of research into making smaller and faster computer chips. Focusing, bending and reflecting light, and then someone thought hey this could be used to make an object invisible A Trek fan I'm sure.

Re: AMAZING PHOTO! scientists closer to creating invisibility cloak

I saw this on the news today, and discussed it with my dad... I REALLY don't see how a cloak could ever work on Earth... think about it... ok... we cloak a plane. Fine. But physically, as an object, the plane is still there... thus, any light hitting the plane, would cast a shadow on the ground, giving away the fact that there IS something there. The same with a person... you can cloak the item itself... but the fact of their physical presence remains, and thus, the uncloakable shadow.

Same principle for a boat-cloak... it would be given away by both visible depressions in the water, not to mention a foamy wake that appears to be coming from nowhere.

Re: AMAZING PHOTO! scientists closer to creating invisibility cloak

With a perfect cloak, a shadow wouldn't be a problem. After all, you're not just blocking the light emitted from the object, you're bending the light from behind it around in such a way that you can see what's on the other side without distortion. So shadows are no issue.

The depression in the water would be, unless you were able to fabricate the image of undisplaced water on the fly; and that strikes me as even more impossible than cloaking to begin with.

LOL... shadows ARE an issue...

You can bend light any way you want, so that YOU cannot see an object. However... let us say a cloaked airplane flies above you, and passes in front of the sun. The plane is not visible to you... but the fact remains, that a physical object is still crossing the path of the sun's light, and thus, will cast a shadow.

Think of it this way... you have a tree in the middle of a vast grassy plain. You want the tree to seem invisible, so you cover that tree with wrapping paper, that exactly mimics the grassy plain around it. However... the tree is still a physical obstacle, and when the sun's light shines on it, the shadow of the tree will still be cast.

Yes, but the sun's light is being bent around and past the plane, just like the reflected light from the sky, and ground, and clouds, and everything else that the plane is inconspicuously failing to occult.

Re: AMAZING PHOTO! scientists closer to creating invisibility cloak

A perfect cloak would cause the object not to block or significantly deflect (once it leaves the immediate area) any photon, so shadows wouldn't be an issue.

If you were simply projecting an image equivalent to what's on the other side but not using the actual photons that are hitting over there, then intensity information could be lost and shadows would result.

If your cloak redirects the light properly then it doesn't merely 'cover' the object, but redirects light around it. A bright light shining on the cloaked object would illuminate the spot past the object where you would ordinarily see a shadow. At least in theory.
