Spanish Physics made magnetic "wormhole"

Wormhole («wormhole» or "wormhole") - a hypothetical feature of space-time, which is a kind of "tunnel". Through it can be alleged to stitch through the fabric of space-time, moving quickly from one end of the universe to the other. At least that's what worked wormholes in sci-fi movies like "Stargate" and "Star Trek," and went from this term.

The mechanism moving through a wormhole can be compared with driving dynamics needle that sews directly to two opposite ends of a rolled tissue.

A tempting idea of ​​movement through space excites the minds of not only fans of science fiction, but scientists from the Department of Physics, Autonomous University of Barcelona.

Spanish Physics создали laboratory something called magnetic wormhole . This device, which magnetically connects two regions of space-time. That is, the magnetic field produced in the same region, exactly recreated in another region.



"With the help of modern technology can not create a gravitational wormhole as field control need a huge amount of gravitational energy that no one yet knows how to generate, - stated on the website of the university. - In the field of electromagnetism, however, advances in metamaterials and invisibility allowed researchers to design several designs that allow it ».

The two regions are connected to the tunnel through which a magnetic field is passed, but the tunnel is impossible to detect from the outside. That is, it is visible to the naked eye, but the magnetic field around it is not.

For this purpose special metamaterials and metapoverhnosti, so that the magnetic field source - magnet or electromagnet - appears on the other end of the tunnel as an isolated magnetic monopole. This result is surprising in itself, because the magnetic monopoles, ie magnet with only one pole, north or south, do not exist in nature. It seems that the magnetic field is like moving from one place to another through izmerenieza beyond the usual three-dimensional space.

External magnetic wormhole looks like a sphere, made of several layers. The outer layer has a ferromagnetic surface, a second inner layer made of a superconducting material, and is within the scope of the ferromagnetic sheet rolled into a cylinder, joining the opposite ends of the sphere.

Magnetic wormhole "changes the topology of the space, because its internal volume magnetically erased from the space," explains Alvaro Sanchez (Àlvar Sánchez), lead author of the research.

Last year, the same group of researchers has developed a magnetic fiber, in which a magnetic field is passed from one region to another. However, its magnetic field could be detected, but now it was isolated and achieved complete "invisibility».

Experts say that the magnetic wormhole can be used in medicine. It becomes possible to carry out magnetic resonance imaging of patients in a more comfortable environment for them. That is, the patient is treated in one location and detection of the magnetic field is in another. Besides, it is possible to scan several parts of the body of the patient simultaneously.
