It turns out that they are more complex thermodynamic systems than previously thought.

Physicists at the University of Sussex (UK) have shown that black holes exert pressure on their environment. The discovery was published in the journal Physical examination d In the last week.

According to Carl Schwarzschild’s theory, the authors of the study discovered when looking at the additional figure that appeared in the equations for quantum gravity corrections for black hole entropy, without electric charge or angular momentum.

When the strange result of the equations came up as a topic in the middle of last year’s Christmas talk, scientists realized that it actually reflected the behavior of the compressive force, and then put pressure on the black holes showing the quantum gravitational force through additional calculations.

This discovery marks another milestone in the study of black holes, as proposed by Stephen Hawking in 1974. Emits heat radiation. Prior to Hawking’s theory, these holes were believed to be dull, marking the final stage of a dying heavy star. Now physicists at the University of Sussex have shown that they have a characteristic similar to temperature and that they also exert pressure.

“Hawking’s historical intuition is that black holes are not black, but have a radiation spectrum similar to that of a black body, creating a perfect laboratory for investigating the relationship between quantum kinetics, gravity, and thermodynamics.” He pointed out Physicist Xavier Colmet, one of the authors of the study.

“If we consider black holes only within general relativity, we can see that they have a peculiarity at their centers, where we know the laws of physics, To breakWhen quantum field theory is incorporated into general relativity – one day “Calmet continued” we get a new interpretation of these strange cosmic objects.

The scientist called his work “a step in that direction,” which “opens up many new possibilities, including the study of astronomy, particle physics, and quantum physics.”
