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

A group of researchers at the University of Sofia have found evidence suggesting that the reason wormholes have never been observed is because they look almost identical to black holes.

In his paper published in the journal Physical examination D, Petya Nedkova, Galin Gyulchev, Stoytcho Yazadjiev, and Valentin Delijski describe the study of theoretical linear polarization from accretion disk which would be around a class of static transient wormholes and compare findings with images black holes.

For many years, scientists and science fiction writers have considered the theoretical possibility of a wormhole. Such an object, theory suggests, it would take the form of a kind of tunnel connecting two different parts of the universe. Tunneling would allow travel to distant destinations in ways not available to spaceships unable to travel faster than the speed of light—shortcut.

Unfortunately, no one ever noticed a wormhole or even any Physical evidence that they really exist. However, because the theory of their existence is so strong, astrophysicists assume that they do exist. The problem is that we either lack the technology to see them, or we haven’t looked for them in the right way.

In this new effort, researchers in Bulgaria suggest that the latter is the problem. They found evidence, via theory, that suggested they could be sitting there in the night sky an ordinary sightand that the reason we don’t see them is because we confuse them with black holes.

The work involved studying wormhole theories and then applying the findings to create simulations, focusing on the polarity of the light such an object would emit – and taking into account the characteristics of the presumed disk surrounding its mouth. They then created both direct and indirect images to show what a wormhole would look like and compared them to black holes; they discovered that they looked remarkably similar.

The researchers noted that it should be possible to tell wormholes and black holes apart by seeing subtle differences between them, such as polarization patterns and intensities, as well as their radii.
