For the first time, astronomers have been able to see the back of a black hole, thus proving that Albert Einstein was indeed right, more than a century later.
Einstein’s general theory of relativity
the telegraph Report that an international team of researchers succeeded for the first time in We see the back of a supermassive black hole 800 million light-years away from our planet. Thus, they were able to prove Albert Einstein’s theory about the behavior of these mysterious celestial bodies.
Use these researchers Extremely powerful X-ray telescopes To study this black hole located at the center of a distant galaxy. These astronomers observed the usual characteristics of a black hole, but they also spotted light, in the form of X-rays, emitting from the far side of a black hole.
for information, Black holes are born when a massive star explodes into a supernova and then collapses on itself. Then it is formed mass of incomprehensible density, sweeping everything nearby. So it should be logically impossible to see the light behind the black hole.
However, the tEinstein’s general theory of relativity predicted in 1915 The gravitational pull of black holes may be so apparent that they will distort the very fabric of space, twist magnetic fields and bend light.
Accordingly, theEinstein’s work confirmed that it is possible to see light waves ejected from the other side of the black hole, due to distortion of magnetic fields, Then it acts like a mirror.
Experts have accepted the theory, but have not yet been able to directly observe the phenomenon. But thanks to modern telescopes and the development of highly sensitive instruments, this is now possible.
Dan Wilkins, astrophysicist at Stanford University, and studied the mechanics of the destruction of atoms and electrons by a black hole, as well as the resulting X-rays.
Looking at the data, he saw what he expected, which was X-rays emitted directly to Earth from the core of the black hole. corn Also noticed unexpected echoes after a short time. They were X-rays that were projected in the opposite direction from Earth’s, but were reflected by the black hole’s magnetic field.
This discovery was published in nature, proves once again that Einstein was right and supports the theory of general relativity. the Professor Roger Blandford of Stanford University, co-author of the research, said:
Fifty years ago, when astrophysicists began to speculate about the behavior of a magnetic field near a black hole, they had no idea that one day we would have the technologies to directly observe it and see Einstein’s general theory of relativity at work.
The task of characterizing and understanding these celestial bodies continues and will require further observations. Part of this future will be The European Space Agency’s X-ray Observatory, Athens (Advanced High Energy Astrophysics Telescope). As a member of the laboratory of Steve Allen, professor of physics at Stanford University and particle physics and astrophysics at SLAC, Wilkins is involved in developing part of the wide field imaging detector for Athens. Wilkins said:
The mirror is much larger than we’ve ever had on an X-ray telescope and will allow us to get high-resolution images with much shorter observation times. So the picture that we’re going to start getting from the data now will become much clearer with these new observatories.
