  • Wormholes were theorized in 1935 by my buddy Al Einstein and his pal Nathan Rosen as part

  • of the theory of general relativity. They were called Einstein-Rosen "bridges," and

  • are thought of as holes through space-time. Wormholes have never been spotted, though

  • one Russian researcher believes he could spot them with a radio telescopebut it's never

  • been done. Until now, sort of.

  • Scientists at the Autonomous University of Barcelona have created a magnetic wormhole

  • that appears to transfer a magnetic field through quote "an extra special dimension."

  • Magnetic wormholes aren't space-time wormholes, but they are a similar concept. Space-time

  • wormholes are a manipulation of gravitational energy, which we don't YET know how to do,

  • whereas magnetic wormholes are manipulating electromagnetic energy. Which we're really

  • good at. Using metamaterials (something that gave me a headache on DNews before) the scientists

  • were able to create a tunnel of magnetic energy last year, and this year they made the tunnel

  • invisible. See, while "normal" space-time wormholes connect two points in this (or other)

  • universes through an unseen bridge, but this wormhole connects two magnetic fields through

  • an unseen bridge!

  • It's really key to point out, that if you looked at the wormhole, you'd see it. It's

  • not invisible to the human eye, just to magnetic sensing. A normal magnet has two poles, North

  • and South, and they're opposed, with a magnetic field connecting them. In this case, their

  • wormhole separated the poles, singling them out, creating a monopole -- something that

  • does not happen in nature. Researchers can't tell where the magnetic field that connects

  • those monopoles is, which gives the illusion it's in a "special dimension." This device

  • makes a monopole pop into existence, with no detectable connection to that pole on the

  • other side.

  • Manipulation of magnetic fields is used for Magnetic Resonance Imaging at hospitals. MRI

  • machines use giant magnets to force the protons inside our bodies to align, then use radio

  • waves to knock them around, causing them to show up on the scans. MRI scanners are very

  • sensitive to other magnetic interference, and any metal can ruin the image and be dangerous

  • to the occupants; because it's basically a giant electromagnet. Not to mention people

  • have to slide into that claustrophobia-inducing tube. With this new magnetic manipulation

  • technique, MRI machines might be built which could scan multiple things at once without

  • interference, and wouldn't need one massive magnet. Using a magnetic wormhole MRI they

  • might be able to do surgery and scan at the same time!

  • Plus, the manipulation of electromagnetic fields isn't just big business in medical

  • scienceRemember way back in 2007 when Bush was president

  • and I was a server at a popular chain Italian restaurant? A study in Physical Review Letters

  • made a big splash when it found if you could manipulate electromagnetic energy in such

  • a way, to create an "invisibility cloak," and that is essentially what these Spanish

  • researchers have done! They hid a magnetic field's distortions from the outside, by using

  • metamaterials, to create an invisible electromagnetic wormhole.

  • In the end, this wormhole can't move anything from one place to another, and, like much

  • scientific research, doesn't do anything super practical at the moment, but it IS a proof-of-concept

  • for some future technologies and could be used for things we haven't even thought of

  • yet. On top of that, it's a great simulation of the gravitational wormhole we sci-fi addicts

  • know and love! So, when we finally learn to manipulate gravitational energy on a massive

  • scalewe'll have a few more theories to work with.

  • If you're more into the mystery of gravitational wormholes, Dr. Ian O'Neill and I did a podcast

  • over on TestTube Plus all about black holes, wormholes, white holes and really insane physics.

  • It was a great series!! (soundup-link to playlist) There's also a link in the description if

  • you're on mobile, OR if you're more of a radio person, check it out over on itunes! We took

  • all five episodes from YouTube and smushed them into one kick-ass black hole podcast.
