This new post from the scientist Experimentor_4u reports on a recent new device which has been developed to create a ‘magnetic wormhole’. This wormhole can transmit the magnetic field through a magnetically invisible path from one point in space to another, effectively cloaking the magnetic field so it becomes invisible from the outside. While not an actual space-time wormhole as proposed by Albert Einstein and Nathan Rosen back in 1935, this is more of an ‘invisibility cloak’, a realisation of something that was initially proposed in the journal ‘Physical Review Letters’ in 2007. The device acts just as a wormhole would, however, as if the magnetic field were actually travelling through an extra dimension.
No-one has as yet observed a naturally occurring wormhole as predicted in the general theory of relativity, however this device can transmit the magnetic field through space on a magnetically invisible path. This acts just like a wormhole in that the electromagnetic waves are hidden from view from the outside. You can read all about what a wormhole actually is and about the device itself in our infographic, or watch the video to see how this device actually works.
Follow up posts will look at the first proposals of the possibility of wormholes, now dating back to almost a century ago.
