Xinfan Technology News, Beijing time on August 27, leaked news, among all astronomical concepts, black holes may be the most bizarre one. The density of a black hole is so high that even light cannot escape it, like a huge harvest of darkness and terror. Since the general laws of physics are not applicable to black holes, black holes seem to be created for science fiction. However, numerous direct and indirect evidences show that black holes do exist in the universe.
Einstein's prophecy
Black holes are the inevitable result of Einstein's general theory of relativity.
The German astronomer Karl Schwarzschild first predicted the existence of black holes in 1916, and believed that this was the inevitable result of Einstein's general theory of relativity. In other words, if Einstein's theory is correct (all evidence points to this), then black holes must exist. The research of Roger Penrose and Stephen Hawking has strengthened the theoretical foundation of the existence of black holes. His research has shown that any sky that collapses into a black hole will form a singularity, and the laws of traditional physics all fail at this point.
Gamma set line wool
The observing equipment on the ridge has detected some gamma line hairs produced during the birth of the black hole.
In the 1930s, the Indian astrophysicist Subramanyan Chandrasekha conducted research on the end of the star’s nuclear fuel exhaustion. He found that the final result depends on the mass of the star. If the star is very large, for example, the mass has reached 20 times that of the sun, the dense core of the star (the mass of the inner core can be as high as two or three times that of the sun) will continue to collapse inward until it becomes a black hole. The collapsing speed of the stellar core is extremely fast, and it takes only a few seconds to rejoice. During this period, it will release amazing energy in the form of gamma hair, which is equivalent to the total energy released by an ordinary star in a long lifetime. The telescope on the ridge has detected multiple gamma line hairs, some of which are emitted by galaxies billions of light-years away, indicating that we have really observed the birth of black holes.
Injecting gravel waves
The picture is a conceptual drawing of gravel waves drawn by the artist. The gravel attraction between the two black holes will form ripples in time and space and spread outward in the form of gravel waves.
Black holes are not always lonely. Sometimes they also appear in pairs and revolve around each other. The gravel attraction between the two black holes will form ripples in time and space and spread outward in the form of gravel waves. This is also one of the predictions put forward by Einstein's theory of relativity. With the help of observatories such as LIGO and Virgo, we now have the energy gravel to detect gravel waves. In 2016, scientists announced for the first time the discovery of gravel waves produced by two black hole raccoon dogs. Since then, we have detected multiple gravel wave events. With the continuous improvement of the detector's proliferation, scientists have also detected gravel waves generated by events other than black hole raccoon mergers, such as the similarity of black holes and neutron stars.
Invisible companion
The picture is the imaginary picture of the trajectory of several days in the Samsung system HR6819.
The high-energy events that can produce gamma line hair or gravel wave are all high-energy events that occur in a short period of time, and may be seen in half of the universe. But considering their nature, most black holes are undetectable. Black holes do not emit any light or radiation, so they can hibernate silently in space. Astronomer Yuben is not aware of their existence. However, there is a way to detect their existence: using the boulder-inducing effect caused by black holes on other stars. In 2020, when astronomers were observing the seemingly ordinary binary star system HR6819, they found that the trajectories of the two stars are somewhat weird. Unless there is a completely invisible sky tick in the system, this phenomenon can be explained. Calculating its mass joy, the researchers realized that there is only one truth: this Tianti must be a black hole. It is only a thousand light-years away from the ridge, located within the Milky Way, and is the closest black hole to the ridge discovered so far.
X set line
Black hole CygnusX-1 is the huge blue shore companion star beside the eclipse.
In 1971, when scientists were studying a double star system named CygnusX-1 in the Milky Way, they first observed evidence of the existence of black holes. The X design lines produced by this system are extremely bright, but these design lines do not come from the black hole or its visible companion, but are generated by the accumulation disk formed when the black hole harvests the stellar material. Just like the binary star system HR6819 just mentioned, astronomers can also use the trajectory of the visible star to estimate the mass of the invisible sky tick in the CygnusX-1 system. The final calculation result is about 21 times the mass of the sun. Taking into account the small space occupied by the day, it can only be a black hole, and Yuben does not need to consider other possibilities.
Supermassive black hole
There is also a supermassive black hole in the center of the Milky Way.
In addition to the black holes formed by the collapse of stars, there is evidence that there may be some supermassive black holes lurking in the center of galaxies, millions or even billions of times the number of the sun, and they may have existed since the early days of the universe. . In the so-called ”active galaxies”, the evidence for the existence of these supermassive black holes is spectacular. NASA pointed out that there is a ring of rhinoceros disks around the black holes in the centers of these galaxies, which will release extremely strong radiations covering various wavebands. There is also a black hole in the center of the Milky Way, because we have observed that the rotation speed of stars in this area is astonishing, as high as 8% of the speed of light, indicating that they must be revolving around a small but extremely massive sky. The results of Meqian's estimation believe that the mass of the central black hole in the Milky Way is about 4 million times that of the sun.
