I wonder how ong it wil take for cloaks to be sold in stores such as Wal Mart. That would be a sweet trick for people to use for halloween. But then people would come up with glasses to see them or what not!
James Bond, 007! Know how much we could use this in war, having the ability to attack someone right in front of them without them seeing you. Not like its needed but we could really use this!

I thought it said that you were learning Chinese, Japanese, and Korean in your hobbies profile. Or wait... Maybe it said learning bits and bits of those languages... But after I read you speaking japanese on the shoutbox I thought that you could read other languages.

Yeah, I'm learning them as a hobby. I can read Korean and tell you what it sounds like, but I wouldn't have any clue what I'm saying.. yet >_>

Why do we need this?

Showing off? Magic tricks?If this is actually possible, which sounds pretty true it could very much likely be some way to find out how and where to use it.
For military purposes, Have some GI's fly into the enemies base on a jetpack and have the cloak on keeping them completely invisible and shutting down their nuclear warheads, it would save the world from nuclear war and bring it back to stealth and close combat.
Unfortunately, it doesn't really protect you from detections such as infrared and heat vision.
A combination of various technologies that block detection would be useful, however (think of it like one of those black stealth bombers that can't be detected on radar and are virtually unseeable at night), in creating a virtually 24/7 undetectable craft. The only problem is that it wouldn't really be able to communicate with other aircraft.
Well, it isnt invisible on radar, it just shows up of the size of a bird, which would basically be overseen by most radars, but radars made for seeing things like this would think of it as a bird, but they would probably look more into it, the height that it flies at also help it! It basically works like the so called 'invisible warship' which appears on radar as a 40-50 foot fishing boat, which it is really over 600 feet long!
Let me quote my post from the uh... previous topic on invisible things (
Meta materials).
QUOTE
Invisibility for everybody. We didn't destroy oursleves with the atomic bomb, so let's try this stuff instead.
I didnt see that topic about invisibility so mine was just off the top of my head, I was answering Wilhelms question of why we would need this. We dont really need this, its just a valuable gain in technology!
Ahem...
The news:
This Korean invisibility cloak is rather old news. Its just a camera set up behind the wearer that projects an image onto the cloth. It was made quite a few years ago. Its not meta materials, and functions more like a television then anything else. NOT REAL CLOAKING...
Meta materials, which actually have the capability of cloaking (FOR REAL) are a reality but they could never be implemented in such a way to be used as a cloak. (For one they are made of long strands of metal, which would be unable to have the flexibility in clothing while still being able to bend light properly. Also the larges meta material with cloaking capabilities on frequencies of electromagnetic light, is only the size of a cocktail coaster. (mind you there isn't yet one for visible light as that requires smaller rings of material.) They are still working out many kinks in the new materials capabilities. This information on meta materials is good since October 19th, from a former chief scientist of Microsoft.
I heard that scientists could teleport a molecule, idk details
teleporting molecules has nothing to do with an invisibility cloak.
Rantent: When I was talking about meta materials, It was the information from the United States cloaking.
One thing is that DT_Battlecruiser certainly is not the only person who is able to read Korean because hundreds of thousands of Koreans love Starcraft seeming that I am also Korean. Also, Korea wasn't the first country to use this technology, and I believe it was actually a Japanese scientific research company that actually developed this invisibility cloak.
Well they may haev been the first to try to make it, everything acn be perfected, just like the idea of making a fake image in front of and around the object is full of flaws, the U.S.'s idea is fool proof once we master it. Bending light abround an object has released no such flaws, we just need to find metamaterial that will allow more than one color at one time. And make it able to be seen from the inside out.
No matter what anybody says i still think the idea of being invisible is pretty sick.
*off topic*
However i heard that they found a way to split an atom with a laser to create nylon and are looking for ways to make other materials -- anybody know anything about that?
Besides the cammera effect of proyecting an image onto a piece of cloth, it is, by theory, impossible to achieve invisibility.
First off, light is a far different concept than what has been discussed in this thread. Light does not consist of the colors that we can see, light is just a small area in the electromagnetic spectrum that contains electromagnetic waves that have the exact properties that our eyes are tuned for. Thats why we can't see light above violet or below red.
So we have electromagnetic waves with particle-like properties impacting the invisibility cloak. These waves will come by all sorts of directions and angles and thus they will amplify themselves, either cancelling themselves to 0 amplitude, meaning the wave ceases to exist, or achieving a much larger lenght in amplitude and shorter wavelenght. Since light also behaves like a particle, when two photons collide (I do not know the specific physics behind this, but I do know that particles never collide, their electromagnetic field repels them, as discovered by Rutherford) they will reflect, and an electromagnetic wave with the wavelenght of waves we can see will eventually come out and thus we see it. This is one of the reasons us humans emit so much infrared radiation, combined with our high body temperatures.
Now we have Einstein's photoelectric effect. If a wave with more energy than v of a certain metal impacts the atom, the atom will then release the electron. Now considering the materials this cloak could be made of, it is certain that there must be some sort of metal there in order to reflect light around it. No non-metal has the ability to reflect light so we can assume that there is indeed metal in the cloak. Waves being reflected (assuming the cloak works) will amplify the waves to many lenghts and then electrons would eventually be released, ionizing the atoms and then chemistry takes over since new molecules would be formed by the new ions, thus, making the cloak ineffective.
Light cannot bend, it can be reflected or refracted but you cannot make it go around objects.
To achieve invisibility, one must bend light. Light, or to be correctly stated, electromagnetic waves travel by the space around us. To achive this, one would have to bend the space around then by increasing their gravity to infinite and making a black hole (let's not even get started on the shape of the hole). This black hole would have to be so small to an extent that the exponent would be insane, this is so that the hole in space doesn't start pulling all the objects around it. But, you would then need millions of holes small enough to cover you around all your volume but then the holes in space would join creating a bigger hole and it renders it impossible.
Unless there is a theory that I don't now of, it is impossible to achieve invisibility by bending light.
Edit: Hard to explain all the graphical models in my mind.
This is why they use a metamaterial that would not reflect the light back at the perosn viewing. The idea bending light is just telling the person looking at the object that there is nothing bouncing back at them. So it is basically looking around the object. This metamaterial can make it like there is nothing there.
In theory, one could vibrate so fast that the human eyes cannot catch such movements. That would be invisible.
Ya someone could also become 1 atom wide and become invisible but these things are just impossible. Actually you could also be some 200 atoms wide and be invisible too.
Actually it is possible. Having a suit that vibrates so fast would render it invisible.
But wouldnt it have to vibrate wider then the more than the width of the person wearing it, if id vibrated only 2 inches to each side. Only the outside 4 inches would be invisible while the rest of the middle of ther person would be visible.
Gravity is a weak force. Massive electromagnetic force around a person's body might cause it to bend light. ( or maybe even space! )
People say that bending light is impossible. Well in space we believe that a black hole can stop time, we already know that black holes can bend light. So whats the complication?
