Recently, Einstein's black hole theory was finally confirmed. The pictures of black holes exploded the whole astronomical science community. Black holes are also celestial bodies in theory. Some scientists speculate that it is formed by rapid compression after the death of a massive star, but its mass is very large, almost trillions of times that of the sun. Strong quality produces strong attraction. Even light can't escape the bondage of black holes. According to scientists, almost all matter will be swallowed up by black holes. However, when scientists observed through astronomical telescopes, they found that there were celestial bodies around the black hole. 、

Why is this? In fact, if you think about it carefully, the reason is very simple. As mentioned earlier, a black hole is actually a cosmic object. For example, it works in the same way as our solar system. The sun is the largest star in the galaxy. Eight planets, including the earth, orbit the sun. Why is the earth not swallowed up by the sun? We can find the answer through Newtonian mechanics. According to the explanation of Newtonian mechanics, due to the centrifugal force, the star deviates from its rotation center, forming inertia, and the star always moves around the center. This is why the moon always goes around the earth, but its mass can't be compared with that of a black hole, so it needs a lot of centrifugal force to go around the black hole.

As long as the celestial body does not exceed the horizon of the black hole, a certain speed may appear. This speed must reach a limit, that is, superluminal, so only the speed of celestial bodies exceeds the speed of light can they not be swallowed up by black holes, and the distance of black holes must be far enough. This distance is over 20,000 light years. At a recent American astronomical conference, astronomers at the University of California discovered a black hole in the Milky Way. A black hole is surrounded by smoky glass. It looks like a huge gas cloud, but its orbit is more like a star.

So astronomers infer that these strange stars may be made up of small pieces of stardust. They are rapidly approaching the black hole. They may be because the gravity of the black hole attracts two massive stars close to each other. The two stars finally collided and eventually formed a dust star object. After the collision, the two celestial bodies merged and continued to expand but maintained a certain speed. This process may last for a million years, and finally form the form that people have discovered.
