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 like black holes.

In their paper published in the journal physical review D, Petya Nedkova, Galin Gyulchev, Stoytcho Yazadjiev, and Valentin Delijski, accretion disc It sits around a class of static traversable wormholes and compares its findings with images Black Hole.

For years scientists and science fiction writers have wormholeSuch an object, hypothesis It would take the form of a tunnel of sorts connecting two different parts of the universe. Traveling through a tunnel would provide travel to distant destinations in a way not available to spacecraft, which cannot travel faster than space. becomes possible. speed of light— by taking shortcuts.

Unfortunately, no one has ever observed a wormhole. physical evidence that they actually exist. Yet the theory of their existence is so strong that astrophysicists assume they exist. is.

In this new effort, Bulgarian researchers suggest the latter is the problem. They found evidence to suggest, via theory, that they may be sitting in the night sky. plain sightand the reason we don’t see them is because we mistake them for black holes.

The work required studying wormhole theory and applying the results to create a simulation. In doing so, emphasis was placed on the polarity of the light emitted by such objects. Also taken into consideration were the properties of the disk supposed to surround its mouth. We then created both direct and indirect images of what a wormhole would look like and compared them to a black hole. They found them very similar.

The researchers pointed out that they should be able to distinguish between wormholes and black holes by looking at subtle differences such as polarization patterns, intensities and radii.
