“This is the sacred grail of theoretical physics.” Is the key to quantum gravity hides in this new way of making black holes?

The first step towards quantum gravity, the “Holy Grail of Physics”, can hide in a quantum recipe to cook black holes.

This is the proposal of new research results, which gives Einstein 1916 -heavy theory, which is known as the “general theory of relativity”, quantum corrections. Black holes are relevant for this, since they first theoretically emerged from the solutions for the Einstein field equations that substantiate general theory of relativity.

This quantum correction leads to a new recipe for the production of black holes and an indication of the path to quantum gravity and an association of the two dominant physics theories.

While the general theory of relativity is the best model that we have of gravity and the universe on large standards and quantum physics is the best description of the subatomaria, these theories do not agree. This is because despite the fact that both have been around for about a century and a variety of painting have been refined and confirmed that there is still no theory of “quantum gravity”.

This despite the fact that quantum physics is responsible for the remaining three of the four basic forces of the universe: the electromagnetic force, the strong nuclear power and the weak nuclear power.

However, quantum physics and general theory of relativity have something in common; Nor can it explain what happens in the heart of black holes.

“Black holes are regions in space in which gravity is so strong that nothing can even escape. “However, there is a singularity in the center of the black holes in which the laws of physics, as we know them, collapse.”

With these singularities, the density of the black holes goes into infinity. Physicists do not like infinitely because they are not physical, and when they occur, it is the failure of the equations that support the laws of the universe.

This singularity in the heart of black holes suggests that the theory of general theory of relativity is incomplete and what could be missing is the quanta gravity.

“We believe that general relativity only works on large or macroscopic scales, but that they have to be replaced on very short distances or microscopic scales by a quantum theory of gravity that unites Einstein’s equations with quantum physics,” said Calmet. “This is the sacred grail of theoretical physics.”

Is the ‘sacred grail’ in the heart of the black holes?

Physicists have been looking for a recipe for quantum gravity and a union theory for some time. The string theory, which replaces particles with “strings” subatomar vibration, has developed as a leading theory that combines general theory of relativity and quantum physics and thus leads to quantum gravity.

However, there is currently no way to experimentally check this theory. In addition, it is based on the universe that has at least 11 dimensions, and there is currently no evidence of dimensions about the three dimensions of the room and one dimension of the time.

Surprisingly, the lack of a uniform theory was surprisingly no obstacle. All you had to know was that every proposed theory in Einstein’s gravity theory had to fit on large standards.

“Although we do not yet have a theory of quantum gravity, we know that everything that this theory may be, a string theory or something completely different, but the general theory of relativity has to correspond to macroscopic scales,” said Calmet. “This information is sufficient if modern methods are used in quantum field theory to carry out calculations in quantum gravity without needing the underlying theory of quantum gravity.

“With these techniques, we can calculate corrections in Einstein equations that must apply to every theory of quantum gravity.”

What Calmet and colleagues have found is that in addition to black holes that emerged from the solutions up to the equations of general relativity, also “quantum solutions” for black holes.

“We can produce these solutions analytically close to the event horizon, the outer light -fitting surface of the black hole and far from the black hole,” he said. “A disadvantage of using our approach to quantum gravity is that we cannot build our solutions close to the singularity, since here the full knowledge of quantum gravity is required.”

This means that the team cannot recognize whether its quantum recipe for black holes leads to the same morphology for black holes as that from the general theory of relativity.

“It is still important to have new solutions for black hole in quantum gravity that generally do not exist,” said Calmet. “These new solutions are not just changes to the old – they are completely new black holes that exist in a quantum gravity world.”

Therefore, the researcher of the University of Sussex believes that this work is still a step to understand how the quantum mechanics and gravity work together.

Unfortunately, even Calmet does not yet know how the two potential recipes of black holes, general relativity compared to quantum gravity, could be differentiated. This is because we can only watch black holes from large distances.

“The astrophysical black holes that we observe could be described very well by our new solutions as the general relativity,” concluded Calmet. “If the two theories collapse at large distances, it will be difficult to propose tests that can distinguish between the two types of solutions.”

At least for the moment, the secrets of quantum gravity can be guarded violently by black holes.

The research of the team was published on June 19 in a letter journal in which the borders of physics were examined.
