Researchers suggest that wormholes may look almost identical to black holes
Polarization in a vertical magnetic field for wormholes with different redshift parameter α. Each color represents the observed polarization of the orbits located at r=6M (outer ring) and r=4.5M (inner ring) for a particular wormhole solution with α∈[0,3]. The polarization for the Schwarzschild black hole is given with a black dashed line as a reference. The angle of inclination is θ=20°. credit: Physical examination D (2022).

A group of researchers from Sofia University found evidence that suggests the hole has never been observed because it looks almost identical to black holes.
In his article published in Physical examination D, Petya Nedkova, Galin Gyulchev, Stoycho Yazadzhiev and Valentin Deliyski describe the study of theoretical linear polarization by accretion disk which would be located around a class of static traversable wormholes and compare the findings with images of black holes.
For many years, scientists and science fiction writers have considered the theoretical possibility of a wormhole. Such an object, theory suggests that it will take the form of a kind of tunnel that connects two different parts of the universe. Propulsion through the tunnel would allow travel to distant destinations in ways inaccessible to spacecraft unable to travel faster than the speed of light– by taking a shortcut.
Unfortunately, no one has ever observed a wormhole or even one physical evidence that they actually exist. Yet, because the theory of their existence is so strong, astrophysicists accept that they do exist. The problem is that we either lack the technology to see them, or we haven’t been looking for them in the right way.
In this new effort, researchers in Bulgaria suggest that the problem is the latter. They have found evidence, through theory, that suggests they may be sitting there in the night sky ordinary lookand that the reason we don’t see them is because we mistake them for black holes.
The work involved studying the theories of wormholes and then applying the findings to create simulations, focusing on the polarity of the light that would be emitted by such an object – and also taking into account the characteristics of a putative disk surrounding its mouth. They then created both direct and indirect images to describe what a wormhole would look like and compared them to black holes; discovered that they looked strikingly similar.
The researchers noted that it should be possible to distinguish wormholes from black holes by noticing subtle differences between them, such as polarization patterns and intensities, as well as their radii.
