study Oxford university Prove, for the first time, that Albert Einstein He was right when he said there was an area in black holes As it is no longer possible to avoid falling into the cosmic body. The so-called regression zone is located around black holes, in which matter stops rotating around the hole and falls directly into it.
The research also indicated that this region exerts one of the strongest gravitational forces ever identified in the galaxy. The conclusions were published in the scientific journal Monthly Notices of the Royal Astronomical Society This month, it is part of a broader university investigation into these cosmic objects.
The newly published study focuses on smaller black holes closer to the galaxy Land. The researchers used X-ray data collected by NASA, the NuSTAR telescopes, and NICER.
Contrary to theory Isaac Newton Because of gravity, Einstein argued that upon approaching a black hole, particles could no longer spin safely in a circular manner. Instead, it hurtles toward the center of the black hole at close to the speed of light.
The university researcher says: “This is the first look at how plasma taken from the outer part of the star falls into the center of the black hole, in a process that occurs in a system ten light years away.” The Oxford University physicist who led the study, Andrew Mummery, said in a statement to the institution.
He points out that Einstein's theory had already predicted the existence of this final dive. But, in this study, this was the first time that science had been able to prove that this process occurred.
Astrophysicists are trying to understand what happens near the surface of a black hole. To do this, they study disks of material orbiting celestial bodies. Scientists even debated whether the regression zone was detectable.
Mummery believes the new study represents an advance in this field by allowing them to investigate the area around them. The researcher says the latest particle dip shows how matter responds to gravity in the strongest possible way.
African Millimeter Telescope
While one group is studying small black holes closer to Earth, another research team from the University of Physics at Oxford is building the African Millimeter Telescope, targeting massive black holes.
This second team is part of a European initiative whose funding has so far reached 10 million euros. These resources will partly fund PhD scholarships at the University of Namibia in partnership with Oxford. The telescope will be the first to provide snapshots of large black holes at the center of the Earth. milky wayWhere the Earth is located, or even beyond it.
Thus, scientists hope to be able to see the “event horizon” of these celestial bodies, which attracts material from space towards its spiral center as the black hole rotates. This represents an unimaginable source of energy. The team hopes to film them running for the first time.
