as @kenbellows said ... it is not a wormhole.
It is an illusion of a wormhole. It is not creating a real path in the space-time. It is a magnetic phenomenon that makes it look as if two points got connected and a magical tunnel was established. Pretty cool experiment, though.
Authors suggest that this illusionary wormhole could also be used to making smaller MRI machines and patients don't have to go through the claustrophobic experience of current machines. Super Awesome .. Giant machine in one room and the patient is sitting on a couch in the other room, and being scanned.
Oooh wait - what if police investigation rooms get designed this way, such that as they ask you questions and from the other room, they are actually scanning your brain for changes in the signal pattern ?? - Crazy idea. Aight, I am re-pivoting as of now. Scanning as a Service...lol
- hyperliner 11y agoYou just made my brain explode. Thank you for enlightening me.
- knodi123 11y agoBrain explosions are a definite possible side effect.
- KingMob 11y agoFormer cognitive neuroscientist here. In all seriousness, if this technology were dropped in today, it would be hard to use surreptitiously; you still need to immobilize the head to get a good fMRI signal at current speeds. Also, interpreting a brain scan to determine lying is way beyond our actual abilities (though sadly, there are Indian courts and companies doing just that, despite the warnings of the neuroscience community).
- Vexs 11y agoStill better than being inside those incredibly loud machines. I expected a "spinning" noise of some kind, not the jackhammer concerto. Also, I had no idea courts in India were using that as a detection method; that's insane. I hope to god they don't use it as absolute evidence...
- s_q_b 11y agoYou know that our security services and, more disturbingly, our prosecutors' offices still use the polygraph, right?
- qCOVET 11y agoya but when polygraphed .. you are aware that you are getting polygraphed. but secretly scanned from an adjacent room... that my friend is in the realm of science fiction...lol
- s_q_b 11y agoMy point was more that before condemning the Indians, we should remove the log from our own eye.
- duaneb 11y agoIt's getting there. Polygraphs are still useful to measure ~~psychological~~ neurological response, so we might not see them disappear. I could certainly still find it convincing if corroborated with a psych expert who understands how to read it (and when NOT to draw a conclusion). The idea of discerning a lie with any reliability with a machine and no access to any direct evidence is absurd, though.
- KingMob 11y agoYeah, the polygraph is no better. Homeland Security approached my old prof about building a field lie detector using just a computer and RTs. As part of their visit, they talked about their lie detection abilities, their motion-sensitive chairs, specially-built rooms, and super-investigators. I just rolled my eyes.
- adamio 11y agosounds like a modern version of the floating = witch test
- duaneb 11y agoAlso, IIRC from "lying experts", there is no such thing as an objective lie. If you have no anxiety about the lie (I think I was reading about Lance Armstrong on this), or you don't think you're lying, you can easily pass a polygraph test. You can habituate your brain to follow certain patterns even if you do know you're lying. I suspect there will never be a "magic lie detector" with any reliability for people who understand what is happening or take preventative measures.
- ethbro 11y agoI heard similar and figured it was a signal to noise problem. In that it was impossible to reliably eliminate false positives (the anxiety of someone normal being polygraphed) while still detecting trained liars (who minimize their anxiety while still lying).
- WaxProlix 11y agoSure, and untraceable communications - you put a wire on a spy and they're radio-ing everything home with nothing to indicate it. Battleships get their orders and there's not even a chance of interception, let alone decryption. Do these illusory tunnels bypass things like Faraday cages? What about a ton of mass? There's a lot of military and consumer applications here, and a ton of potential privacy benefits (an unseen wifi network, who knows -- the list goes on). If you want to get rich off this, brain scanning is not the first market to pursue.
- webjprgm 11y agoIt sounds like you need a physical device between both ends. So you couldn't have untraceable radio-like communication. You would just follow the path of spheres like a wire. But yeah, if you could teleport a magnetic field across long distances with nothing in between you would get both communication and, probably more interestingly, power transfer (induction charging). Depending on the properties of whatever hypothetical device accomplishes this.
