For the first time, astronomers have been able to see the back of a black hole, proving that Albert Einstein was indeed right, more than a century later.
Einstein’s general theory of relativity
From telegraph Report that an international team of researchers passed for the first time We see the back of a supermassive black hole 800 million light-years away from our planet. This enabled them 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 at the center of a distant galaxy. These astronomers noticed the usual features of a black hole, but they also saw light, in the form of x-rays, emanating from the other side of a black hole.
to get information, Black holes are born when a massive star explodes into a supernova and then collapses on its own. Then it is formed mass of incomprehensible densityWipe everything around. So it makes sense that it would be impossible to see the light behind a black hole.
However, the tEinstein’s general theory of relativity predicted in 1915 The gravity of black holes can be so pronounced that it distorts the structure of space, twisting magnetic fields and bending 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 the distortion of magnetic fields, Then it works like a mirror.
Experts accepted the theory, but were not yet able to directly observe the phenomenon. But thanks to modern telescopes and the development of highly sensitive instruments, this is now possible.
Dan Wilkins, an astrophysicist at Stanford University, 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. Maize I also noticed unexpected echoes After a short while. 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 general theory of relativity. the Professor Roger Blandford of Stanford University, co-author of the study, said:
Fifty years ago, when astrophysicists began speculating 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 put Einstein’s general theory of relativity to work. to see.
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 Steve Allen Laboratory, professor of physics at Stanford University and particle physics and astrophysics at SLAC, Wilkins has been involved in developing some Generated imaging detector for Athens. Wilkins said:
The mirror is much larger than we’ve ever had on an X-ray telescope and allows us to take high-resolution images with much shorter observation times. So the picture we’ll get from the data now will be much clearer with these new observatories.
