Wormholes – are they really the stuff of Science Fiction?
We have two articles in this issue for you. The first is all about how magnetic fields may travel undetected through space, and the second is just how that might be useful.
What would really get interesting is if we could create a device that envelopes us in a magnetic field and allows us to “punch a hole” in space, maybe we can open a door (as in the Star gate TV series) on one planet, and step through it onto another. Or … perhaps even make warp drive a reality.
But in our frame of reference, the laws of physics simply will not let us travel faster than the speed of light. So without getting into warping the fabric of space-time and black holes, the engineering feat of the century would be to find out how to make a device that could use wormhole technology.
Fascinating read and well worth the share
Wormhole Illusion Causes Magnetic Field To Move Through Space Undetected
August 20, 2015 | by Jonathan O’Callaghan
Scientists have developed a magnetic system that mimics the behavior of a wormhole – theorized to allow space-time to be bent, and vast distances to be traveled in an instant – but it absolutely is not an actual wormhole, so don’t get too excited. However, what they did, which was to make a propagating magnetic field invisible, is actually very interesting. You can get excited again.
The research, by a team from the Autonomous University of Barcelona (UAB), was published in the journal Scientific Reports. They describe how they created a small sphere about 45 millimeters (1.8 inches) across, made of a spherical ferromagnetic (one that can become magnetized) surface, a spherical superconducting layer, and an inner ferromagnetic sheet wound in a spiral. The superconducting layer was made of superconducting strips glued to a sphere, and the entire device needed to be submerged in liquid nitrogen for the superconductor to work. The magnetic field was supplied at one end by a current passing through a coil.
When the magnetic field entered the sphere at one end, the researchers showed how it would appear at the other end as an isolated monopolar-like field – but within the sphere itself, there was no trace of the magnetic field …
“It disappears in one point and reappears in a different point, as if it were travelling through another dimension,” lead researcher Alvaro Sanchez added to IFLScience.

Why is this important? It means that the magnetic field could travel from one side of the sphere to the other without producing any noticeable effects. If you placed a magnet inside the sphere, it would not be influenced by this propagating field at all. Of course, in this case the magnetic field is actually very much there in the sphere – it’s just not detectable. In an actual theoretical wormhole, an object would disappear at one point in space-time and reappear at another …
