‘Electromagnetic Wormhole’ Possible with Invisibility Technology
October 15, 2007From Physorg.com:
In the study, which is to appear in the Oct. 12 issue of Physical Review Letters, Allan Greenleaf, professor of mathematics at the University of Rochester, and his coauthors lay out a variation on the theme of cloaking. Their results open the possibility of building a sort of invisible tunnel between two points in space. “Imagine wrapping Harry Potter’s invisibility cloak around a tube,” says Greenleaf. “If the material is designed according to our specifications, you could pass an object into one end, watch it disappear as it traveled the length of the tunnel, and then see it reappear out the other end.”Current technology can create objects invisible only to microwave radiation, but the mathematical theory allows for the wormhole effect for electromagnetic waves of all frequencies. With this in mind, Greenleaf and his coauthors propose several possible applications. Endoscopic surgeries where the surgeon is guided by MRI imaging are problematical because the intense magnetic fields generated by the MRI scanner affect the surgeon’s tools, and the tools can distort the MRI images. Greenleaf says, however, that passing the tools through an EM wormhole could effectively hide them from the fields, allowing only their tips to be “visible” at work.
The “tips” would be at the end of “long, thin blades of invisible grass” and would appear as “thousands of pixels” floating in the air. Good acid trip, ay?
Invisibility technology linked with wormhole tech is novel and a pretty amazing concept. And I guess the math is solid too.
If a person were a UFO, conspiracy theorist crackpot like me were to say that this could be a basis for UFO technology, the individual would require a rubber-room hotel reservation, right?
Time will tell.
Crazy physics here. And I have no idea how these guys came up with the math to prove it.
Any math geniuses out there?
Yeah… 2+2=22! Sorry, Marine… womanizing and brawling took priority over mathematics. I liked Algebra for the art of it, other than that, what do you do with it?
Sounds like the “Philadelphia Experiment” in miniature. Yet another one of Tesla’s discoveries exploited.
I can picture concepts in my mind and make good guesses, but as for putting it down to figures and formulae, I’m out of my league. Einstein et al seemed to have that gift.
Black holes are just oversized gravity sinks. Gravitation (whatever that is) is the key to inter-dimensional travel AND invisibility, as neutron stars are effectively ‘invisible’ to the naked eye, visible only by the distortions they produce to their backgrounds; i.e. the star field.
If we were able to master gravitation, all talk of FTL propulsion would be irrelevant and moot.
The thing I’ve never been able to wrap my tiny peabrain around is with worm holes is, how do you control where you come out at the other end? Or, it purely random?
I mean, in aviation, you have a compass and in space flight you have star charts but what is the source of navigation with worm hole technology?
I don’t think the article mentioned gravity at all. But they did mention the wormhole would require the use of an “exotic” material. What that is, I don’t know. Historically, physicists have postulated that “negative” matter/energy would be required to hold a wormhole open. But nothing was mentioned about that either. Just electromagnetic energy. And that does imply Tesla Tech.
Tesla was one of the greatest practical engineering/theoretical geniuses of all time. Too bad Edison screwed him over and had all the PR to cover it up. We’re still rediscovering stuff Tesla dreamt up a hundred years ago!
From what I’ve read and studied about wormholes over the years Christopher, both fact (theoretical) and fiction, one would need to send a probe or powerful telescope looking through the wormhole to check the stars at the other opening to get a bearing and a fix.
Stephen Baxter and Sir Arthur C. Clarke a few years back wrote a story about a company that was able to grab wormholes from the quantum foam and expand them using Casimir Engines. Once expanded, you could make observations through them. I imagine you could probably do the same with these “invisibility” wormholes.
“Teleportation” achievable once we’re able to create pure organic (with genetic imprint) material.
That’s the premise that they employed in “Time Tunnel” technology, Dad. They could open a wormhole wide enough to get a picture of the universe in another place and time.
Trouble is, without a familiar reference point, even a probe wouldn’t help you if you couldn’t decipher the constellations from the perspective of looking at them from the opposite end of the universe!
I like the spome method of exploration, utilizing a big, relatively slow-moving asteroid or even a huge ‘ark-like’ vessel (Starlost) that wouldn’t require a return to Earth. You wouldn’t have causal or relativity problems to deal with, either. You might even luck out, and run into some highly-advanced race that’s already done all the work, and benefit from their experience. (If they decided to let you live!)
Over time, even a large spome could attain extremely high velocities in flight. I think that from a purely unromantic and scientific standpoint, any other method of space exploration is just an unnecessary burden on research and development, when man could use existing or soon-to-be extant technology and get going with that.
Very intriguing.
What of the challenge of keeping them stable and recreating the worm hole to return to the point of departure?
UH: I actually suggested that to Quasar9 on his site last week when he posted a thread about an asteroid deflection system that used small satellites with inflatable mirrors that directed concentrated sunlight at one end of the asteroid to boil off reaction mass and move the object away from Earth. I suggested the same system could be used to build space habitats. He’s the one who actually suggested strapping engines on. Helium3 fueled fusors powering ION drives would work great, if you weren’t in a hurry. You can refuel in the Kuiper Belt, spread out the colony there and cross over to Proxima Centauri’s Kuiper Belt. Repeat, wash and rinse. Great for dissident groups.
Christopher: Here’s a cut from the article; “To create cloaking technology, Greenleaf and his collaborators use theoretical mathematics to design a device to guide the electromagnetic wavesin a useful way. Researchers could then use these blueprints to create layers of specially engineered, light-bending, composite materials called metamaterials.
He goes on to say that these metamaterials would be able to hold the wormhole “tunnel” open. Pretty effin’ wild and it does involve some exotic Tesla Tech (even though it’s not mentioned).
This is getting too deep for me to comprehend.
Just give me Warp 2 and a one-way passage to Alpha Centuari and I’ll be happy. *wink and smile*
Yeah too deep, so dad what d’you think about my earlier post?
Christopher: Warp speed my friend *thumbs up*!
lowerpericles: What do you mean by “pure genetic material”?
Do you mean that humans have to “purify” themselves mentally and physically before we have skills like teleportation? Or do you mean through genetic engineering?
If you’re talking about eugenics, I do not support that meme. It is anathema.
Transfer of Organic/ Non-Organic material thru digital signals from point A to B. By means of genetic/ blueprint digital reconstruct. Non-Organic is in our daily lives already i.e fibre optic, radio wave etc as medium; but Organic (protocol: in exact schematic/ pure form to prevent mutation) transfer/ “teleportation” none achieved yet. So maybe one day… a Sentient with optimum neuro enhancement configuration may able to pin point the exact resonance or whatever!
Thanks for the reply
lowerpericles: Greg Egan, an Australian sci-fi author and computer scientist, has proposed that theory through many of his works. In fact, it sounds like you already have read some of his work.
A quantum entanglement “teleportation” system would require the scanned object to be destroyed while being uploaded and sent to its destination. Upon arrival, the beamed object (or subject) would require usable reconstruction material to rebuild the body before the uploaded personality can be downloaded into it.
There are going to be many religious and philisophical debates in the future concerning this I’m sure. I think a Singularity will happen before any of this will happen though, so the argument might be moot.
Clone: [Human brain (synthesize tissue with exact neuro mapping) (nano embed), the rest of the body act as survival jumpsuit (nano embed) therefore subjective] — Transfer of data in encrypted digital signatures. Reconstruction platform in form of like “Stasis cell/ cocoon” specimen maintained and not destroyed (failsafe measure).
Imagine in near future. A clone/cyborg (part of human ascendancy) as the first ever to step planet Mars. It’s not a bad idea really, just send a space prob as builder firsly (the journey will take like several months), then just beam up configuration from Earth to Mars once the receiver platform is functional. I wonder if Nano-helper may be able to “hitch-hike” photon? That would be a gash! No need Space prob just beamed it up thus interstellar jump.
Egan? Well thanks never knew
