‘Haired’ black holes? Albert Einstein’s theory may explain

Recently, a non-peer-reviewed article published in the preprint journal arVix explored the topic in more depth. in the perspective of a study of black holes that current scientists have not discovered.

In Albert Einstein’s Theory of General Relativity, black holes can be studied by the curvature of space-time, but scientists have focused on investigating the curvature of black holes.

According to an approach created by physicists John Wheeler and Jacob Bakenstein, ‘black holes have no hairs’; This is an analogy that explains black holes’ lack of distinctive features – like a person’s hair; One can be blonde, the other can be brunette, straight, curly, etc. The theory explains that since these large objects have three identical properties, there is nothing to distinguish them from each other: These; mass, electric charge and angular momentum.

The concept of a ‘hairless black hole’ is based on Einstein’s theory of general relativity, but scientists in the new study explain that they can also apply relativity to focus on the ‘twisting’ of the black hole. Curvature of spacetime is widely used because It was the first concept created by Albert Einstein, but both interpretations are considered “mathematically equivalent”.

“We examine the teleparallel formulation of non-minimally coupled scalar Einstein-Gauss-Bonnet gravity. In the teleparallel formulation, gravity is defined by torsion rather than curvature, causing the usual Gauss-Bonnet invariant expressed through curvature to decompose into two separate invariants generated from torsion.

Black holes have ‘hair’

The torsion approach is also known as ‘teleparallel’ gravity due to the study of parallel lines of black holes. From the comment, Scientists in the new study managed to find some ‘hairs’ in the studied black holesS; Of course, it’s not about the hair, it’s about the elements that don’t look much like black holes.

Researchers explain this ‘Hair’ is actually the presence of a strong scalar field near the event horizon of a black hole — in this case it’s a scalar field, but other black holes may have other ‘fuzz’. In any case, scientists will continue to study the subject to learn more about the ‘fuzz’ of black holes.

“We also find that by taking variations with respect to the scalar field, we can notice that for some couplings the invariants TG and G can cause the scalar field to narrow by a hair… In a limiting case, we can also do a scalar field with a strong scalar field near the horizon, but with a scalar charge approaching zero. “We find black holes,” the study concludes.
