Mathematicians Design Invisible Tunnel
New calculations show how to make an electromagnetic "wormhole" — a tube that is invisible from the sides but allows light to shine down the center. The practical applications are a ways off, as even the design of a spherical invisibility cloak has not advanced beyond working (in theory) for a single wavelength of visible light.
anyway, it seems to work on the website.
Not to be a party pooper, but is there really any application for this tunnel? You can't see it, you can't see out of it, and you need to build it so it can only go to places you can already go.
In NJ we already have tunnels that seem to do nothing. We call them the Holland Tunnel & Lincoln Tunnel.
"advenced"? "are a ways of"? That futuristic language must be from the other side of the wormhole!
I'll be impressed when they make invisible tubes for Internet2.
We're all going to die. i intend to deserve it.
Ok... Let the penis-size jokes ensue!

" New calculations show how to make an electromagnetic "wormhole"--a tube that is invisible from the sides, allowing light to shine down the center unseen." Unfortunately, this is NOT the defenition of a wormhole. What the articel describes is a physical tunnel, that is simply invisible from the outside, not a wormhole that links 2 distant places through a much shorter distance.
If anyone is interested, I found a photo:
this is a good application for the army. a series of tunnels and your moving trucks and cargo without the enemy seeing them. all they would know is that you have the tunnels but would'nt know exactly what your moving.
I don't quite see how anyone can claim they designed such a thing. It is sort of like saying Klein designed a bottle that holds everything on the outside on the inside. Of course a Klein Bottle is impossible to construct, sure it's an interesting mathematical idea but it's not anything you can make in reality, so it's senseless to say it's been designed. Let's just say it's been imagined.

That should be obvious: it will have great implications for the Internet, which - as we all know - is a series of tubes. The tunnel carries light, so it can work like a fibre connection, and we can identify the endpoints.
:-)
I want to drag this out as long as possible. Bring me my protractor.
Finally we can build an invisible network of fiber optic cables!
Valkyrie is about to die! Wizard needs food -- badly!
So now you can *KLANG* Chuck Norris on the head with a tube, and he won't see it coming?
I don't think one would have much time to enjoy the moment though, 'cause he will round-house-kick the tube into your navel.
If you mod this up, your slashdot background will turn into a beautiful sunset!

I mean, what's the use of this technology if they're not putting it to good use
Scully: Should we arrest David Copperfield?
Mulder: Yes we should, but not for this.
Why don't we prove that instead?

hell, yeah. now we'll be able to download pr0n without others seeing.
Do not. Touch. Down.
is now a series of invisible tubes
Joebert ! you're late !
No I'm not sir, I got an early start cleaning up inside the tube.

Just think: we can now play hide and seek in public. Lets make tunnels to make it more exciting! Sounds like Harry Potter with all the invisibility, no? Lets face it: there are no practical applications for this invisibility tunnel, at the moment. When a valid need for something like this can be proven, then resume the project.

Democrats or Republicans. They are both taking us to the same place and they are not afraid of us anymore.
I heard about this project when it was first introduced a few years back. I actually know one of the fellas working on the project. I remember the biggest problem with the project was getting the tunnel actually invisible. Since they were working under a government grant they had a specific mandate to make the tunnel energy efficiant and environmentally friendly. So they brought in a team of chemists who insisted the tunnel would work better if it was painted black and filled with solar energy collectors. The tunnel wound up being extremely energy efficiant but they couldn't actually get through the damned thing without struggling over all the equipment jammed in there. It's good to see the mathematicians managed to bring some reason back to the project. My friend there complained every day about those solar collectors.

A biologist, a physicist, and a mathematician are sitting in an outdoor cafe. They watch two people go into a building across the street. Shortly thereafter, three people come out.
"Hmm," says the biologist. "It looks like they reproduced."
"Nah," says the physicist. "There was obviously error in our initial measurement."
The mathematician looks up from his coffee. "Who cares? If another person goes in, it'll be empty."

I have no idea what an invisibility cloak could be good for.
God spoke to me.
I shoved a Maglite up my ass, battery end first. Can't see it from the sides, and you can only see the light from one angle.

I hope flying cars never come about. I don't trust random people to not fly their car into my living room.
One application I can think of: Video privacy. Everyone's most likely seen the advertisements for the "Sonic Ear" or similar doodad. "Watch TV without disturbing your partner's sleep!" The ads usually claim. However, whenever I heard this line, I usually replied mentally: "What about the flashing/flickering light from the television?" Well, it seems to me that this would answer that question. Then again, I've had a long day at work and my brain is a tad on the soft side right now...
Why would you? It is already barely visible as is.

a tube that is invisble from the side but allows light to shine down the center.
wouldn't a tube-shaped region of empty space fit the same description ?
also it seems weird that the article makes no reference at all to the size of the proposed tube. are we talking like a millimeter ? ten feet ? the wavelength of red light ?
You sure seem to be keen on other men's penises.
If its invisible from the sides, how do we keep backhoe operators from digging it up?

If they can only make a single color, such as red, go invisible, can they not wrap an object in a red sheet or something? :)

Of Experimental Science against Applied Phisics.

Invisible technology!
After this article, I'm starting to get the hang of it. Like just now, I have invented an invisible miniature nuclear reactor. It also takes up no space. I plan on using my new invisible reactor to power my next invention, the invisible flashlight! It shoots an invisible beam of light over 50 miles through any kind of weather.
I guess I can use that to find Wonder Woman's invisible airplane when it gets lost. Man, I'm telling ya, this invisible stuff is going to be the wave of the future!

Balderdash!
As they say, "tooth can be stranger than friction".
One future application of this technology is covered in the book The Light of Other Days by Stephen Baxter and Arthur C. Clarke. In it, a company develops a way to spy on anyone, anywhere using light wormholes. It completely changes society because suddenly privacy is non-existent. The book is a very interesting read, and it's available on Amazon for a penny.
Slashdot's first reaction to VMware
Oh, but a mirror IS required. Anyone have a link to a mirror or cache?
(and regarding your comment, w/o the smoke, how are u going to see the light? unless its pointing directly at you which probably isn't a good thing)
The CG illustration shows a portal in the middle of a road. Stupid because cars would crash into the tunnel.
Also arxiv is I thought where anyone can submit. So TFA saying a major journal is disingenuous because it is popoular but not peer reviewed, unless I missed something.
The tunnel is not nonexistent, cloaking only works at a certain frequency range. Probably it could be found through lower frequency vibration (seismic/sonic) or higher energy perhaps (i.e. X-ray). Right?
So I take it the idea is basically saying (though I have only read part of the paper yet) that you can wear a cloak of invisibility and even open the side of it, and if you flare it open still nobody can see you except head-on.
There is one neat thing where they say a magnetic field entering one end of the tunnel would look like a magnetic monopole at the other end. Also looks like it might be useful in building telescopes.
Actually there are several applications I can think of dealing with fiber optics. Currently if you can get access to the fiber, you can monitor signals going through it without having to actually splice the line, so noone knows the line has been tampered with. This would prevent such an attack on a fiber optic network, great for improving security on a network.
Also if it cannot be seen from any side, it means it loses no light during transmission, like current fiber does, removeing the need for repeaters over long distances of fiber.
These are just the two things I thought of immediately. This does not mean that it is work with cost of actually building, but they are possible applications.
Perhaps this could be a good replacement for fiber.
Um, you know when there's a temperature inversion between you and the nearest big city? And you start picking up radio and TV stations from that city that you normally never receive? Nature made you a temporary tunnel for radio waves. p Your typical fiber optic fiber does something much like this. The fiber has a gentle gradient of index of refraction from the center out. So light ends up traveling by the quickest path-- very close to down the exact center. Older fibers depended on light bouncing off the insides, zig-zagging its way down the fiber. That worked, but there were too many possible paths and the bits would end up coming out the other end slightly jittered in time.

military communications security. It might not be useful for troops in the field, but it might work well between bases and ships at sea. Might even be tenable for laser communications in aircraft.
Of course... this all assumes that you only need the metal ring(s) at the end points as portrayed in the article picture. That much wasn't clear to me from the summary.

i've designed a special light-sensitive cloaking device that, when in the absence of light, renders the wearer completely invisible to the naked eye.
