Astrophysicists at Princeton University have made an important discovery about black holes. They discovered that the energy near black hole M87* points outward rather than inward. This brings to an end a long-standing debate in the scientific community. Black holes are known to capture everything around them. However, in reality, this is not always the case. “Black holes are defined as objects from which nothing can escape, but one of the surprising predictions of Einstein’s theory of relativity is that black holes can lose energy,” said Elliot Quatert, a professor of astronomy at Princeton University. “There is,” he explains. Since the 1970s, scientists have known that magnetic fields can drain energy from rotating black holes, but the mechanism behind this process remained unknown. Recently, researchers at Princeton University confirmed that the energy of black hole M87*’s event horizon points outward. This discovery suggests that the black hole’s loss of rotational energy is the source of powerful energy flows known as jets.

According to former Princeton University postdoctoral researcher Aleksandr Lupsaska, “These jets are like Jedi lightsabers, a million light years long.” They can reach distances up to 10 times the size of the Milky Way. Masu. Their findings were published in the Astrophysical Journal. Astrophysicist Andrew Chael is the paper’s lead author. He and co-author George Wong were members of his team for the event His Horizon and His Telescope and played a key role in developing models to interpret black holes. The researchers discovered that the direction in which the magnetic field rotates around a black hole determines the polarization observed in images of the black hole. From this we can draw conclusions about the direction of the flow of energy – from the black hole to the field or vice versa.

George Wong, a scientist in the Princeton Gravity Group, compares the energy released by M87* to the energy that caused the Earth to explode thousands of times per second over millions of years, producing TNT. Scientists are convinced of the relationship between the flow of energy and the direction of the magnetic field, and suspect that the energy comes from a black hole. This hypothesis will be tested when the next generation Event Horizon Telescope is brought to market. Despite the convincing evidence presented in the study, the scientists stress that it has not yet been proven that the rotation of the black hole is the source of the energy for the extragalactic jet. However, the energy levels shown by their model are consistent with the energy levels required to drive the jet.
