Researchers at Stanford University have recorded for the first time X-rays from the other side of a black hole, like this one Wissensmagazin Scienexx the.
In the case of black holes, due to the immense gravity, there is such a strong curvature of space-time that we can look forward and backward at the same time.
This confirmed the predictions of Albert Einstein’s general theory of relativity. Note created in Nature Magazine chest.

Despite extensive research, black holes remain a mystery to us. We know that the mass of black holes is compressed into a narrow space so that they exert a very strong gravitational pull. Anything that enters this area will be permanently swallowed.
Black holes appear as shadows in the image. In 2019, researchers managed to capture the first image of a black hole. Now, about two years later, scientists at Stanford University have made another observation that tells us more about black holes. For the first time, researchers were able to observe X-rays from behind a black hole, thus Wissensmagazin Scienexx the.
Astronomers’ observations were pioneering. This confirmed the phenomenon predicted by Albert Einstein. Formulating his theory of relativity in 1915, he hypothesized that black holes – viewed from the side of a bright accretion disk made of adsorbents – must cause space-time to warp. In astrophysics, an accretion disk is understood as a disk that rotates around an object that moves matter toward a center. It consists of ionized gas, which is called plasma, or atomic gas. The curvature of the black hole must be so strong that light must deviate from the back of the black hole and become visible from the front, according to Einstein’s assumptions. This allows us to look forward and backward at the same time.
Simulations like this one show what the effect of curvature on the sides of the accretion disk looks like.

Dan Wilkins, an astronomer from Stanford University, and his team have now been able to record this assumption with the help of a special X-ray telescope. Note created in Nature Magazine chest. The team was able to capture radiation from the back of the black hole in the first galaxy, Zwicky 1,800 million light years away. Therefore? About 60 million kilometers from the black hole, the interaction between the incoming plasma and the magnetic field causes intense radiation. This burst of X-rays is partially reflected by the accretion disk, and illuminates again with a slight delay.
In the next trajectory for Wilkins and his team, the researchers made further observations: the second X-ray burst appears in terms of spectral properties and is timed as an echo pause from the first X-ray burst. In addition, the researchers found that the energy of individual eruptions must be reflected in different parts of the accretion disk. “The analysis of the X-ray flare revealed brief flashes of photons, properties that match the emission from the back of the black hole,” said Dan Wilkins. “These are light particles that bounce off the other side of the disk and are bent and amplified by the strong gravitational field around the black hole.”
With this observation, Einstein’s assumption can be confirmed: black holes cause curvature so strong that both forward and backward can be seen at the same time. So observation is another step by scientists, which brings light into darkness (black holes).
