Polarization in the vertical magnetic field for wormholes with different redshift parameter α. Each color represents the observable polarization of the orbits located at r=6M (outer ring) and r=4.5M (inner ring) for a given wormhole solution with α∈.[0,3]🇧🇷 The polarization for a Schwarzschild black hole is given by the black dotted line as a reference.

A team of researchers at Sofia University has found evidence that the reason wormholes have never been observed is because they look almost identical to black holes.
In an article they published in a magazine Physical examination D, Petya Nedkova, Galin Gulchev, Stoytcho Yazadjiev, and Valentin Delijski describe the study of theoretical linear polarization. storage disk would settle around a class of static traversable wormholes and compare findings to images. black holes🇧🇷
For many years, scientists and fiction writers a wormhole🇧🇷 Such an object, theory suggests that it will 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 possible for spaceships that could not move faster. speed of light— using a shortcut.
Unfortunately, no one has ever observed a wormhole or even one physical evidence that they really exist. Still, the theory of their existence is so strong that astrophysicists think they do exist. The problem is that we either don’t have the technology to see them, or we haven’t looked for them properly.
In this new effort, researchers in Bulgaria suggest the problem is the latter. Through theory, they found evidence that they could be sitting there in the night sky open viewand the reason we don’t see them is because we mistake them for black holes.
The work involved studying wormhole theories and then applying the findings to create simulations, highlighting the polarity of the light such an object would emit, as well as the properties of a hypothesized 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; they found that they were strikingly similar.
The researchers noted that it should be possible to distinguish subtle differences between wormholes and black holes, such as polarization patterns and intensities, as well as by noting their radii.
