The geometry of the lens through the wormhole source represented by the blue ball W, in which the corresponding potential is (14). O denotes the observer and S is the light source. The image is represented by I. α is the deflection angle and β is the angle between the wormhole and the light source. ˜β is the angle between the image and the light source. b is the impact parameter that is perpendicular to the dotted line OS. Dls, Dl and Ds are the distances of the angular diameter. For simplicity, we set Dls≈Dl. z ranges from S to O. Credit: Physical Review D (2023). DOI: 10.1103/PhysRevD.107.024022
En su artículo publicado en la revista Physical Review D, Petya Nedkova, Galin Gyulchev, Stoytcho Yazadjiev y Valentin Delijski describen el estudio de la polarización lineal teórica de un disco de acreción que estaría situado alrededor de una clase de agujeros de gusano transitables estáticos y compararon los hallazgos con imágenes de agujeros negros.
Previous theoretical efforts have suggested that wormholes could exist in the universe, described as tunnels of a kind, connecting different parts of the universe. Some in the physics community have suggested that it may be possible to traverse such tunnels, allowing faster-than-light travel across the universe. The researchers note that previous research has shown that black holes have such a strong gravitational pull that they can bend light, a phenomenon known as microlensing. They then wondered if wormholes, if they exist, also exhibit microlensing.
Proving that wormholes cause microlensing would, of course, involve first proving that wormholes exist. Still, the researchers suggest that general relativity and other theories could shed light on whether the idea is possible. In their work, they discovered that it was possible to calculate how an electrical charge associated with a wormhole would distort light passing through it. They also found theoretical evidence that wormhole microlensing would be similar to black hole lensing, which they say would make it difficult to tell the two apart.
A seemingly intractable black hole paradox first proposed by physicist Stephen Hawking could finally be resolved by wormholes through space-time
The group also noted that previous research has shown that black holes can split the light that passes through them, producing different numbers of copies of an object behind them. The math for a wormhole, on the other hand, suggests that it could only generate three copies of an image behind it: two that were the same and dim, and a single bright one. And if such copies do exist, they have the possibility of large magnifications (the researchers’ calculations showed an magnification of up to 100,000 times), much more than in the case of black holes.
This difference, they suggest, could be a way of telling the difference between black holes and wormholes. They also point out that if their theory is correct, wormholes could be a new tool for studying objects that are too far away to be seen with other methods.
