The “interesting pattern” fulfills the predictions of the legendary physicist and was observed when scientists looked at X-ray bursts emanating from a supermassive black hole in a galaxy 800 million light-years from Earth.
The telescopes then recorded an unusual case: successive flares of rays, which were smaller, later had different “colors” from their predecessors and came from behind the black hole. When they analyzed further, the researchers realized that the smaller emissions are back-reflective echoes of the larger ones, “ folded around the black hole on the other side of the accretion disk (a rotating structure made up of dust and gas falling on it). strong source of gravity).
“Any light entering a black hole cannot escape from it, so we shouldn’t be able to see anything behind it,” said Dan Wilkins, an astrophysicist at Stanford University.
However, the strange nature of the black hole made it possible to observe it. “The reason we see this is because a black hole bends space by bending light and magnetic fields around itself,” Wilkins explained.
This may mean that after more than a hundred years, it will likely be possible to gather evidence of the truth of the phenomenon described by Einstein.
Fifty years ago, when astrophysicists began speculating about how a magnetic field would behave near a black hole, they had no idea that one day we might have the technology to observe Einstein’s general theory of relativity and see it in action, said Roger Blandford, Professor Physics at Stanford University and co-author of the study.
