Theoretical physicists argue that black holes admit vortex structures

Light can't escape from a black hole. The first direct observation of black holes took place in 2015.

Physicists have conducted many studies to understand these fascinating objects. There are many theories about the dynamics of black holes.

Researchers at Ludwig-Maximilians-Universitt and Max-Planck-Institut fr Physik have recently carried out a theoretical study. Black holes should theoretically be able to admit vortex structures according to their paper.

A new framework for black holes has been introduced recently, according to one of the researchers. rotating black holes have not been thoroughly studied until now. They could be the rule rather than the exception.

The recently devised quantum model of black holes was one of the calculations done by Khnel and his friends. The study's main goal was to examine rotating black holes on the quantum level to see if they would admit structures.

Khnel said that rotating Bose-Einstein condensates have been subject to intense studies. We were invited to look for those structures in models for rotating black holes.

Khnel and his colleagues showed how a black hole can be described as a graviton. Previous studies suggest that black holes are stable against the so-called Hawking evaporation, a black body radiation that is thought to be released outside of a black hole's outermost surface.

The researchers showed that in the presence of mobile charges, the black hole's overall vortex traps a magnetic flux of the gauge field, which would lead to signature emissions. New possibilities for the observation of dark matter could be opened by the team's predictions.

"Vorticity is a new characteristic of black holes, which are on the classical level and fully characterized by three entities: mass, spin and charge," Khnel said. Until now, this is what we learned from textbooks. We demonstrated that we need to add more strength.

There is a possibility that the lack of Hawking radiation for black holes is due to the existence of vortices. This theory could lead to new experimental observations and theoretical conclusions.

Black hole structures could explain the magnetic fields in our universe. It is possible that they are at the root of almost all known magnetic fields.

Khnel said that the field of black holes had recently been established. There are a lot of important and exciting questions that need to be addressed. Future observations of merging black holes could open the door to new and exciting quantum aspects of space time.
