Magnetic ‘wormhole’ connecting two regions of space created for the first time

Autonomous University of Barcelona via ScienceDaily:

“Wormholes” are cosmic tunnels that can connect two distant regions of the universe, and have been popularized by the dissemination of theoretical physics and by works of science fiction like Stargate, Star Trek or, more recently, Interstellar. Using present-day technology it would be impossible to create a gravitational wormhole, as the field would have to be manipulated with huge amounts of gravitational energy, which no one yet knows how to generate. In electromagnetism, however, advances in metamaterials and invisibility have allowed researchers to put forward several designs to achieve this.

Scientists in the Department of Physics at the Universitat Autònoma de Barcelona have designed and created in the laboratory the first experimental ‘wormhole’ that can connect two regions of space magnetically. This consists of a tunnel that transfers the magnetic field from one point to the other while keeping it undetectable — invisible — all the way.
