a tube that is invisible from the sides but allows light to shine down the center

The emperor has new clothes. A tube like that is called "vacuum". Can't see it from the sides and it allows light to shine down the center. Where's my research grant?

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.

Scientists develop invisible, weightless clothing that is so thin you can't feel it. One of their first customers has been the King of England, but orders have also been placed by the President and hundreds of middle aged men hoping to impress their wives this Mother's Day.

Could make for a very effective nail if they found a way to sound proof things. People can't see in or out of it, they wouldn't even know it was there except they could not enter/exit it. Would be absolutely perfect for prisons and such.

Much easier to hide than Guatanamo and we wouldn't have to be paying rent to Cuba, either.

AFAIK Cuba tried to remove the lease on Gitmo when Castro found out what the USA was using it for but real estate brokers and lawyers enjoy the same type of power over the Cuban government as they do here.

The one application that struck me is the holographic implications. If you can get light to move to a precise spot in mid-air through an invisible tunnel, you can make objects appear anywhere. No smoke or mirrors required.

That should be obvious (1)

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.

How about a recon vehicle?
Put the tube standing on end around the vehicle. Use fiber optics, small cameras, or other sensors in a periscope so they can see outside the tube. There would also be the possibility of stacking smaller and smaller tubes to form a dome over an object.

                        GNU GENERAL PUBLIC LICENSE
                              Version 2, June 1991

  Copyright (C) 1989, 1991 Free Software Foundation, Inc.
          59 Temple Place, Suite 330, Boston, MA 02111-1307 USA
  Everyone is permitted to copy and distribute verbatim copies
  of this license document, but changing it is not allowed.

                                Preamble

    The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.

    When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

    To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

    For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.

    We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

    Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

    Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

    The precise terms and conditions for copying, distribution and
modification follow.

                        GNU GENERAL PUBLIC LICENSE
      TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

    0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

    1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

    2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

        a) You must cause the modified files to carry prominent notices
        stating that you changed the files and the date of any change.

        b) You must cause any work that you distribute or publish, that in
        whole or in part contains or is derived from the Program or any
        part thereof, to be licensed as a whole at no charge to all third
        parties under the terms of this License.

        c) If the modified program normally reads commands interactively
        when run, you must cause it, when started running for such
        interactive use in the most ordinary way, to print or display an
        announcement including an appropriate copyright notice and a
        notice that there is no warranty (or else, saying that you provide
        a warranty) and that users may redistribute the program under
        these conditions, and telling the user how to view a copy of this
        License. (Exception: if the Program itself is interactive but
        does not normally print such an announcement, your work based on
        the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

    3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

        a) Accompany it with the complete corresponding machine-readable
        source code, which must be distributed under the terms of Sections
        1 and 2 above on a medium customarily used for software interchange; or,

        b) Accompany it with a written offer, valid for at least three
        years, to give any third party, for a charge no more than your
        cost of physically performing source distribution, a complete
        machine-readable copy of the corresponding source code, to be
        distributed under the terms of Sections 1 and 2 above on a medium
        customarily used for software interchange; or,

        c) Accompany it with the information you received as to the offer
        to distribute corresponding source code. (This alternative is
        allowed only for noncommercial distribution and only if you
        received the program in object code or executable form with such
        an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

    4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

    5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

    6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

    7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

    8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.

    9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

    10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

                                NO WARRANTY

    11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

    12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

                          END OF TERMS AND CONDITIONS

                How to Apply These Terms to Your New Programs

    If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

    To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

        Copyright (C)

        This program is free software; you can redistribute it and/or modify
        it under the terms of the GNU General Public License as published by
        the Free Software Foundation; either version 2 of the License, or
        (at your option) any later version.

        This program is distributed in the hope that it will be useful,
        but WITHOUT ANY WARRANTY; without even the implied warranty of
        MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
        GNU General Public License for more details.

        You should have received a copy of the GNU General Public License
        along with this program; if not, write to the Free Software
        Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

        Gnomovision version 69, Copyright (C) year name of author
        Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
        This is free software, and you are welcome to redistribute it
        under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:

    Yoyodyne, Inc., hereby disclaims all copyright interest in the program
    `Gnomovision' (which makes passes at compilers) written by James Hacker.

    , 1 April 1989
    Ty Coon, President of Vice

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Wormhole? (0, Redundant)

imamac (1083405) | more than 6 years ago | (#19013755)

" 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.

I know I shouldn't reply to sigs, but I didn't read that as a sig at first. I was going to agree that given his current situation, an invisible wormhole would present Bush with an attractive exit strategy indeed.

Ideally, one would be able to invisibly travel through the wormhole and emerge from it wearing a flight suit.

Or they could build their tunnels out of metal-shielded concrete, and nobody would see what they are moving either (for a fraction of the price, probably).

Re:military (3, Insightful)

cathector (972646) | more than 6 years ago | (#19015861)

why is this modded 4/interesting ?
you don't even have to read the article. right there in the summary it says "a tube that is invisible from the sides but allows light to shine down the center." (not that the article actually says much more than the summary)

so while i'm sure the military will have an application for this, as they seem to have applications for anything which my money can be spent on, the only things which can be moved thru the tunnel are photons.

Designed?!? (3, Interesting)

sakusha (441986) | more than 6 years ago | (#19013821)

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.

It is not a necessary condition. The 4d klein bottle does indeed have the property you describe, but the 3d "projection" bottles are still perfectly valid: if you bother to trace it, you'd find that they do indeed have only one surface.

Did you people all flunk math? Those are MODELS of a Klein Bottle, not a REAL Klein bottle. The Klein Bottle is a construct that cannot exist in normal 3D space.

Nope, we'll call it a drawing of a cube when defining it... but if someone asks "what is it?" we're liable to just say "it's a 3D cube". That's a common way to use the English language, and for most of us is not hard to understand. The ability to understand flexibly used language is one of the things that differentiates us humans from machines.

Lots of 2D representations of 3D things are referred to as '3D' - take, for example, any game with '3D rendered graphics', ie. almost all of them these days. Common usage is, like it or not, the most reliable way to transfer information.

The article is clearly nonsense. It doesn't explain anything, merely speculates idly about how the tunnel that doesn't exist should work, throws in a few buzzwords, and some general information, and calls it a day. Nothing to see here, just more pageviews for Scientific American.

Beating Chuck Norris (2, Funny)

Tribbin (565963) | more than 6 years ago | (#19013903)

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.

Re:Beating Chuck Norris (-1)

Anonymous Coward | more than 6 years ago | (#19013991)

This comment is so unfunny it deserves a rebuttal.

First of all, referencing Chuck Norris is not an automagic "Funny" +1 mod.

Second, who round house kicks anything into the naval? Throat would have been better. Arse would have even been more funny. (Though still not round house kick quality.)

*sigh*

I just wanted 30 seconds that I shall never get back.

Furthermore, Chuck Norris was BORN with the knowledge that the invisible tube would one day be aiming to intersect with his head, so he took steps many eons ago to ensure that whoever would be responsible for this, would instead be born as a thousand beautiful women who would be too busy fawning over his manliness to do anything so vulgar as to try to swing a big invisible tube at his head.

Re:Beating Chuck Norris (-1)

The tubes are invisible because they are hiding. And it's common knowledge that you can't hide from Chuck Norris.

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.

Cathoderoytube (1088737) | more than 6 years ago | (#19014443)

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 math guy, a physics guy, and a biology guy (5, Funny)

HungWeiLo (250320) | more than 6 years ago | (#19014611)

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."

The practical applications are a ways off? (1)

LouisZepher (643097) | more than 6 years ago | (#19015203)

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...

Re:The practical applications are a ways off? (1)

Invisible Tube (1)

MillionthMonkey (240664) | more than 6 years ago | (#19015739)

You can try to slit my neck with a knife
I'd be watching porn in the afterlife
You can make it so my disks all won't play
I'll be making trouble like you always say
You can try to push a content cartel
As if you still had things you could honestly sell
You can turn our culture music and art
To little squares on cryptographic charts

There has to be an invisible tube
It can't be seen by just any dude
There has to be an invisible tube
For sending mail to senatorial boobs

It blinks all day or it blinks all night
Eigenstates and quantum tangled light
It goes all way with an integer spin
Turning into bits that the pulse brought in

There has to be an invisible tube
It gives free bits to everyone
There has to be an invisible tube
With stuff that plays when the download's done

And you're only going to slow the pace
by private key encryption of the human race
You would bill me for a pretty sunset
You haven't found a way to charge just yet

There has to be an invisible tube
To show us all these people in the nude
There has to be an invisible tube
That can't be seen running to my cube

how's it different from empty space ? (1)

cathector (972646) | more than 6 years ago | (#19015903)

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 ?

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? :)
