Space is so mysterious and enormous that it’ll take your whole life traveling it; still, you won’t be able to explore even the full of the Milky Way Galaxy, our own galaxy! So does this means that we won’t be able to know what’s on the other side of this spooky place?! Well, that’s where the idea of wormholes, also referred as white holes came into play.
Wormholes are shortcuts in the space-time fabric leading us to another universe or another part of the universe is a very short time. Albert Einstein said in 1915 that gravity is the consequence of a warping in space-time. Basically, the very existence of an object curves space and time and creates an impression on the universe around it and the deformation created by it in the space-time give rise to the effects of gravity.
Richard Holman, a physics professor at Carnegie Mellon University said, “Suppose that there are you and another mass. You deform the space-time around you and the mass deforms the space-time around it, and you’re both falling into each other’s wells.”
And now, we have reached the place where all these get connected to the wormholes. Based on the explanation of Albert Einstein and his colleague Nathan Rosen, the wormhole deforms space-time which is twisted in such a manner that so they can create a bridge between two points in space-time.
So, what’s the consequence? A hole, straight or curved, connecting two parts of this enormous and mysterious universe that are extremely far from each other, also it can take you to a parallel universe. The mathematical model of Einstein predicts that wormholes actually exist in the universe but we haven’t found them yet. Luckily, an astrophysicist at Nagoya University, Fumio Abe suggested a very effective way to find a large wormhole, almost enough for a spaceship. Which is to look at the brightness of a star while that is moving in front of a tunnel; if the brightness fluctuates in a peculiar way because of the gravitational lensing, there could be a wormhole.
And when they couldn’t find one, they thought to create one. So what happened? Well, it was a success. Yep, researchers at the Autonomous University of Barcelona created a device which is capable of generating a magnetic wormhole. Which is a spherical device capable to transfer magnetic field from one space to another in space, and it was created were inspired by Professor Allan Greenleaf’s theoretical work.
The hypothesis of Professor Greenleaf established an electromagnetic wormhole’s idea which could transfer electromagnetic waves via a transparent hole between two points in space. With the use of magnetic metamaterial and metasurfaces, the wormhole transfers magnetic field from one point to another in space through a path which is magnetically undetectable.
They’ve said that building the device was very troublesome because all the materials were very problematic and impractical to work with, but they do exist making it easier to find. They worked for about four months to create a real wormhole after they finished the final design.
Result? A three-layered sphere; containing an iron magnet surface and a superconducting matter in the middle with a ferromagnetic cylinder inside. According to them, it is a spatial wormhole for magnetic fields. Thus it can’t transfer matter. But they and other scientists think that in the future, we would be able to create one.
