- solld3th, on 09/04/2008, -0/+29lol see again, just poke a hole in it, no one would care if there was a floating eyeball
- anagoge, on 09/04/2008, -1/+26This title makes my head hurt.
- 1337Einstein, on 09/04/2008, -0/+21That isn't the issue they're seeking to resolve here. The purpose is not to discover or expose cloaked objects, people, etc., but to permit whatever is cloaked to be able to receive incoming light, which would be necessary to see.
- josephbloseph, on 09/04/2008, -0/+16In Soviet Russia, invisibility can't not see you?
- inactive, on 09/04/2008, -0/+15Lol, just realized what you were saying.
Excuse my dumbassery. - nyx210, on 09/04/2008, -0/+14If you look at the image long enough, you'll realize that it isn't very useful for explaining the actual concept.
- zantos420, on 09/04/2008, -0/+13if you have an invisibility cloak, it bends light around you; so if you were to try and observe in or out, the light bending would cause you to not be able to see what was on the other side of the cloak, looking either in or out.
the anti-cloak, as they call it, would allow the person inside (who is otherwise unable to peer out) to see what was on the otherside, effectively creating what we really think of when we think of an invisibility cloak; the ability to only change the fact others cannot see you. - inactive, on 09/04/2008, -4/+13There's not much to get.
For every invention that does something, there's another that screws it up.
Guns: bulletproof jackets: armor penetrating bullets: armor penetrating bullet proof jackets: knife. - bstew22, on 09/04/2008, -3/+12http://www.sciencedaily.com/releases/2008/09/08090 ...
"While an invisibility cloak would bend light around an object, any region that came into contact with the anti-cloak would guide some light back so that it became visible"
so, all i have to do is find the invisible person, and then touch my anti-inivisibility cloak to their cloak, without them KILLING me first. there are no flaws to this plan. - EatChex89, on 09/04/2008, -2/+10Am I the only one who just doesn't get it?
It's like the whole "not not not not not" thing.
But what the hell? - drakenlot, on 09/04/2008, -2/+9This is really interesting, I never paid mcuh attention to invisibility cloaks because of that problem, but this sounds like it would work.
But the article makes it sound like it would cancel the invisibility cloak completely, which makes no sense as to why wear two cloaks that cancel each other out. The documentation they link sounds more liek a one-way mirror, the kind interrogation rooms use. - Ninnux, on 09/04/2008, -1/+8The Klingons figured this out long ago.
- jj101, on 09/04/2008, -0/+7Well done Einstein! Thats the first time I've ever said that in a comment without being sarcastic.
- flamingduck, on 09/04/2008, -0/+7Dugg for floating eyeballs.
- 4rp4n3t, on 09/04/2008, -1/+8Seriously?! I can think of many possibilities...Of course, secreting myself invisibly in the female showers at the gym wouldn't be one of them though - oh no, no, no...
- HonestAbe, on 09/04/2008, -3/+10Guys, these "invisibility cloaks" appearing in the news lately are just ***** sensationalistic journalism. Journalists don't understand the actual scientific discoveries being made, so they make stuff up.
- wunksta, on 09/04/2008, -0/+6but then it would be useless against those that use the same goggles correct?
- inactive, on 09/04/2008, -0/+5what does it disenchant to.
- ShadowPhoenix11, on 09/04/2008, -0/+5wait, if the cloak is invisibly, how do you see it to make it?
- NuFadZoo, on 09/04/2008, -0/+4Science hasn't evolved past cave drawings yet.
- eq2s, on 09/04/2008, -0/+3A practical way to see outside an invisibility cloak would be to equip the wearer with goggles that allow the wearer to see part of the light spectrum that the cloak does not bend. For example; assuming the cloak only bends visible light, the wearer could wear infra-red goggles.
- BlaqReaper, on 09/04/2008, -0/+3My solution would be to mount a tiny translucent camera onto the cloak (maybe near the ends) where it would be the least conspicuous (Like a tiny speck on the floor and not some tiny thing floating in mid air). Then you could have goggles that can transmit what the camera sees to you. At least that sounds more feasible than an anti-invisible cloak.
- stinkybinky, on 09/04/2008, -0/+3i noticed that myself. also, the verbiage they use in the article to explain the concept doesn't work very well either.
- vypergts, on 09/04/2008, -0/+3I had to do a double-take because the headline made me think this was from theOnion.
- jikmo, on 09/04/2008, -0/+3They already have. It's called an invisibility cloak.
- drakenlot, on 09/04/2008, -0/+3It's like dividing by zero.
It's the end of the universe. - eq2s, on 09/04/2008, -0/+3Correct, but those people would need to know there is someone wearing an invisibility cloak and have the goggles. This would be unlikely in some situations.
- FeloniusMonkey, on 09/04/2008, -0/+3RTFA folks!
- cornking, on 09/04/2008, -0/+3am i the only one who read this and thought it was from theonion?
- DulcetTone, on 09/04/2008, -0/+3re: when you're invisible from the outside, the outside is invisible to you.
Ostriches discovered this EONS ago - orangederange, on 09/04/2008, -0/+3sigh...
- xtothepowerofx, on 09/04/2008, -1/+3sry.. cant get behind scientific diagrams that use exclamation points.. it ain't grade 4
- iticu, on 09/04/2008, -1/+342.
- o0joshua0o, on 09/04/2008, -0/+2This is why SEP fields are so much better.
- BXRWXR, on 09/04/2008, -0/+2Is anyone working on "sleeve of wizard"?
- jr93087, on 09/04/2008, -0/+2I'm still searching for the Onion logo lurking somewhere in the corner
- 4rp4n3t, on 09/04/2008, -1/+3Don't judge a book by it's cover - the article is New Scientist...
- BaoUnit, on 09/04/2008, -0/+2LOL, at first I didn't think the hole was for the eyeball
- SkippyDoorknob, on 09/04/2008, -0/+2They got it from the Romulans.
- latrosicarius, on 09/04/2008, -0/+2"But a perfect invisibility cloak guides rays so effectively that none reaches the object within, keeping it in total darkness"
If they can do it with infrared light, you could maybe block heat. use it as a refrigerator - drakenlot, on 09/04/2008, -0/+2Doesn't matter, because the invisibility cloak doesn't allow ANYTHING to go in or out, which is the problem that this is trying to solve.
Basically, before this, anything outside the cloak is invisible to whatever in inside the cloak, you'd only see endless darkness. - myt29, on 09/04/2008, -0/+2You guys need reading comprehension 101.
- mablung, on 09/04/2008, -0/+2first thing I thought as well. It is the wording of the title.
- Milstead1979, on 09/04/2008, -0/+2Thanks for digging this article ... I didn't see it ...
- SkippyDoorknob, on 09/04/2008, -0/+2And you thought it was bad when you dropped a contact lens on the floor!
- xxgracefallenxx, on 09/04/2008, -0/+2mind = blown. who honestly would have ever though we'd even be seriously writing about an actual working invisibility cloak in science journals. I know it's a very long shoot to even make the initial cloak let alone the anti-invisibility cloak to make it useful for every day humans but.. just wow. awesome.
- megamod, on 09/04/2008, -2/+3In the next Harry Potter, is he going to poke a hole through his cloak?
I could think of one or 2 dirty jewish jokes in there... - GetItBuilt, on 09/04/2008, -1/+2For those comments where there is no belief in the invisibly cloak, let me point out that Nano-technology has opened the door to many new frontiers. To review the story published by a universities findings view this:

Then you can start to see how this whole process is possible. Although it might not be here today, they had to say the same thing about a phone people carry in their pocket or a car that could go 100 mph. All things that are basic now, but once thought of to be impossible. Please never limit the human mind. - toyrifle1, on 09/04/2008, -0/+1When using invisible cloaks, do what some blind folks do, whistle to "see". Or would the suit cancel out incoming sound waves?
