The Invisibility Shield

[chuobio]

Assuming that gravitational waves exist, could wave guides ever be designed to shield objects from the gravitational pull of other masses?

[TomNorts]

Forget cars, imagine having soldiers wear this stuff!

[dx3456]

i dont have to imagine it.. play battlefield 2142 :P

[crazyboy0602]

whoa where did it go?!?!

[benesler]

Whoah. ...Imagine all that this will do for espionage, bank robbery and date rape.

I want one.

[msdnvp]

for this to work, they will need a contest video camera footage being projected at the car from another car traveling with it. hmmp looks like another 150 years to go for this thing to work

[dx3456]

they are going for meta materials instead not the projector.

[bossmantd]

very usefull to have on the roads. millions of invisible cars. :)

god save us all lmao

[ilovapples2]

My friend saw something on this on CNN

If this is the stuff there showing us now imagine

all the crap there keeping secret imagine all the

advance crap they have WOAH!!

[beefpelican]

hmmm. that sure is an animation

[IamDiabolik]

yeah ! show us the real thing !

[darris321]

i think the real thing is still in it's nano technology stage

can't do it on big stuff yet i don't think

[durge666]

lol "in it's nano technology stage." This has nothing to do with nanotechnology. It uses metamaterials that bend light around themselves, meaning that they appear invisible to the naked eye.

[darris321]

i didn't mean to say nanotechnology i was doing a research paper on nanotechnology and it kinda slipped out

hehe

i know about all the meta material jazz

but i really don't quite understand it.

would you care to enlighten me?

[durge666]

Metamaterials are materials whose's structure disrupts the flow of light on and near the material, causing the light to literally bend around the material and make it invisible. Metameterials get their special properties from their shape and structure, not from their material. Meaning they can't be found in nature. They can only be made by man.

Hope that helped :)

Achieving invisibility in the optical spectrum does indeed require nanotechnology. The periodic structures must be significantly smaller than the wavelength of the light it intends to negatively refract. Visible light has wavelengths on the nano-scale order. So too then must the periodic structures. Watch Michio Kaku's in depth explanation of the phenomenon on youtube.

[shadow1234810]

@PacoBell indeed my dear friend finnaly someone who understands the geniuses of nanotechnology

[Shiptarjicigani]

that is correct ;)

[alysdexia]

Microwaves are easy to diffract. As for red and better (UV, X, n, etc.), look up Fresnel zone plate[s].

[holiday07]

hope someone can upload an actual video of how this metamaterial cloak works.

[thaylin79]

big deal. If I used a 3d rendering program I could make a car be invisible too. Show me some real stuff and I'll be impressed. Theoretically sure you can do this. Just like theoretically I could seperate the atoms in my body and a wall and pass through the wall. Doesn't mean it's gonna happen any time soon.

[wassup214]

it's actually on the news today that it just did.

[popowic]

Metamaterials are a modern field of scientific research and theoretically they can provide invisibility for the human eye by bending the electro magnetical waves around the object. The animation is crap though not explaining anything.

[elee423]

still pretty cool though

[sid9102]

i don't see how any of this is useful,its just an animation of an invisible car...

[BahumatZero]

Wow, Science really has came a long way, no doubt this tech will be used in wars though. :(

[brassmonkey629]

thats probably what they made it for

[skipopotamus]

war creates the biggest push for technological advancement
