All the stars in the galaxy revolve around a black hole. At the center of our own galaxy, called the Milky Way, is a black hole about 1 million times the size of our Sun, which in astronomical terms is called "Super Mass." The so-called "black hole" has about 230 million stars orbiting it, one of which is our sun, although it is the sun, but in fact it is only one star! But where does the black hole have so much power? Is coming? Does it also get energy from something else?
In fact, black holes are one of the most hidden things in the universe, which is very difficult to find. If the sun of this solar system were to be trapped in a football, this sun would become a black hole. The density of can be calculated by dividing the volume of the substance in it by its volume).
In the above example, the density of the sun (which has a diameter of about 60 million km) will increase after capturing the volume of the football (which has a diameter of about one foot). The value will increase so much that it will not even let light out, after which the sun will appear black due to the absence of light and it will be called a black hole.
Now the question arises that if the black hole does not even allow light to come out then how are the millions of stars orbiting it safe from it? So the answer is that even after a star has formed a black hole, the amount of matter in it remains the same.
Therefore, the gravity of the surrounding stars or planets will remain the same, since the size of the star decreases drastically after the formation of a black hole, the gravity around it will increase to a certain extent that if anything Once the boundary is crossed, it will be impossible for it to return. This boundary around the black hole is termed "event horizon" in astronomical terms.
Scientists claimed that if a star came within or near the event horizon of a black hole, that black hole would first blow up the outer surface of the star and then swallow the whole star as soon as it was seen, but only a few years. Earlier, scientists observed the scene for the first time with the help of special telescopes.
This sight was observed in a pair of two opposing galaxies 150 million light-years away, named "Arp 299" when a star, which is our Sun. About 20 million times larger than, a black hole shattered as it approached, much of the star was swallowed by the black hole but some of the particles scattered around.
Event Horizon causes intense pressure and friction due to gravity, which causes the material to emit powerful X-rays and observable light that scientists have now seen. In addition, some of the star's matter was emitted by the poles of the black hole, whose speed was close to the speed of light, in astronomical terms It is said that these jets were also observed for the first time and it was seen how these jets actually come into existence.
Remember that this scene has been observed to be 150 million light years away from the Earth, which means that now no one knows what will be the condition of these galaxies, but yes, taking into account the condition that was 150 million years ago.
The light has now reached the earth. That is, when this pair of galaxies collided with each other, life on Earth was going through its early stages and man was not even born.

This shows that the predictions made by scientists over the years with the help of physics and mathematics are true and it also shows that today's science is moving in the right direction.
