Einstein's theory of general relativity was confirmed in hairless black holes

A new study in physics shows how Einstein's theory of general relativity continues to make accurate predictions even for hairless black holes.

Physicists studied this duality using a supercomputer to simulate a black hole surrounded by plasma. In a recent study published in the journal Physical Review Letters, they found that even when black holes have a magnetic field, the hairless theorem and Einstein's theory of relativity still hold.

<"Hairless guessing is the cornerstone of general relativity," said Bart Ripperda, co-author of the study and a researcher at the Center for Computational Astrophysics at the Flat Iron Institute (CCA). "If a black hole has a long-term magnetic field, the hairless theory is violated, but fortunately a solution was found in plasma physics that demonstrates the correctness of the hairless theory."

Find that the magnetic field lines around the black hole quickly separate and rejoin. This phenomenon creates plasma bubbles that are energized and grown by a magnetic field and are even thrown into space or swallowed by a black hole.

"Theorists did not think about this because usually Examine black holes in a vacuum. "But in the real world, there is often plasma around them, and the plasma can store magnetic fields, and this must be in line with conjecture from the theory of hairless theory." The confirmation of hair was that scientists found that this evolutionary process rapidly depleted magnetic fields until they completely disappeared. This very rapid decrease occurred at a rate of about 10% of the speed of light, and according to Repreda, this rapid reconnection saved the hairless guesswork.
