Have you heard about the ''Invisibility Cloak''? What do you think of that?

Question

I read about it on yahoo. Science fiction is becoming reality. Once put on, this cloak will make you totally invisible.

Be serious, please. No stupid answers please

Answer 1

i read that too, but don't know how real this is, if it was then that would be pretty cool!

Answer 2

I agree with Paul on the Faraday Cage comment. DuPont has also created a similar material for the Dept. Of Defense. (It makes troops damned near invisible.) I think it's awesome technology, and hope it will be put to good use in the field. Keep in mind it will not modify heat signatures, thus, enabling infra red detection. Airborne particles will also compromise the cloaking material, so it's applications will be somewhat limited in the dessert. I just wish I'd been the brilliant individual who invented it. I sure would like to retire. :)

Answer 3

We had a talk about it one day and concluded that for large objects it would be impossible because light would not completely bend around the object, and thus the object would not appear invisible. I'm no physics buff but the whole concept sounds silly to me, especically in the context of human applications.

Answer 4

i don't completely understand the reasoning they gave in the website. but i was thinking...they have noise canceling headphones, which take the incoming sound waves and create destructive interference to cancel the "noise". well, light has wavelike tendencies...so couldn't they create an "invisibility cloak" that cancels out the incoming light waves with destructive interference?

(I'm not sure if that was what they were saying in the website...either they were too high level for me or the other way).

Answer 5

I suspect you would still be able to see something since this thing is going to be tuned to a given frequency band. The principal reminds me of a Faraday cage.

Answer 6

Hmmm. Sounds good, but the question is that will it work in the real world? You know, rain, dust, bright light, dark,... stuff that might seriously undermine its stability. Have they thought about that... or are they still getting there?

Answer 7

And then you roll to check your armor class and drink a potion of strength before fighting a dragon lol

Answer 8

it's kinda cool cuz u can go were eva u want with no one noticing. it's scary to if someone's stalking you or trying to rob you or sum thing like that.....

Answer 9

i would like to see a demonstration in person.......it's not going to be like it was in the Potter film......it's not theatrics.....so i think you will hear or see or feel something like static

Answer 10

I can't see it working, that's transparently obvious.
