Can be used in areas such as MRI The electromagnetic field emitted from one end enters the "spherical wormhole" and appears at the other end, creating the illusion that the magnetic field does not know where it came from. We usually say that wormholes are equivalent to curling up time and space to create a short circuit between point A and point B. In this week's "Science Report" journal published in the paper on the 20th, physicists have demonstrated a "spherical wormhole" that transmits a magnetic field from one point to another through a path that does not detect the magnetic field. The so-called wormhole refers to a tunnel that can generate shortcuts to other time and space, that is, an imaginary channel connecting two distant regions in space and time. Objects entering the wormhole can return to the past or leap into the future. This highly powerful hypothesis was proposed by Albert Einstein and Nathan Rosen in 1930. But the scientific community has also proposed a theoretical design to create a special wormhole for electromagnetic waves. The degree of bending of the electromagnetic wave propagation path represents the degree of bending of the space, and also represents the extent to which the distance between the two points in the space is shortened. In this theoretical model, the propagation of electromagnetic waves is like passing an invisible channel connecting two points in three-dimensional space. This time, Alvaro Sanchez of Spain's Autonomous University of Barcelona and his research team were inspired by this model to successfully construct magnetic fields using magnetic metamaterials and supersurfaces (materials and surfaces with properties not found in nature). Spherical wormhole." In the researchers' demonstration, the electromagnetic field from one end enters the "spherical wormhole" and appears at the other end, like an isolated magnetic monopole-like magnetic field, creating the illusion that the magnetic field does not come out. The authors point out that their "spherical wormholes" allow magnetic lines of force to pass through their interior while achieving magnetic invisibility. The researchers say the new study has potentially important applications in magnetic-related medical technologies, such as magnetic resonance imaging (MRI). This wormhole is also a non-worm hole. In the past, the cosmic wormhole is like a space-time thin tube. It is a transportation system for interstellar traffic in science fiction, and it is also a natural time machine. Unfortunately, the specific operation cannot be realized. The wormhole in this paper only transmits the magnetic field. Because the magnetic field drilled from the other end gives a sense of “sudden appearanceâ€, the concept of “hyperspace pipeline†of the wormhole is borrowed, so it is also related to those theories. The relationship is zero. But what about it, only practicality, it won. Concerned about surprises
