Now that astronomical observation technology is becoming more and more advanced, we have also begun to come into contact with some "celestial bodies" that open our minds! For example, "black holes".
A black hole is not really black, it is an extremely dense celestial body, and because its gravitational pull is so strong that even light cannot escape, it is called a "black hole".
In other words, in fact, it may be white, but we can't see it, we can only feel it.
A black hole is an extremely dense celestial body, and for a better understanding of it, it can be likened to a "gravitational trap". When an object approaches a black hole, the object cannot escape due to the strong gravitational pull of the black hole, as if it had fallen into a trap.
Of course, I know a lot. But what I didn't expect was that there would be billions of black holes. Even in the Milky Way, there are many black holes.
For now, we are safe.
The most recent black hole was discovered by scientists in 2022 and is called "Gaia BH1", which is about 1,560 light-years away from Earth.
Luckily, it's far away!
At the center of the Milky Way, there is a huge black hole with a mass about that of the Sun, and this black hole is called "Sagittarius A*". In addition, many black holes have been found in other galaxies, some of which have masses
Black holes can be so big that we can't imagine them, like the proportions of an ant and an Earth.
Of course, this is a very peculiar phenomenon! When two black holes come close to each other, the gravitational pull between them becomes strong enough to pull them together. It depends on who is powerful, and whoever has a big appetite can eat each other, and then eventually merge into a bigger black hole. It's like the game we usually play "Snake".
The discovery of black holes has given us a deeper understanding of the nature and mysteries of the universe. Black holes are one of the most mysterious and fascinating celestial objects in the universe, and their existence and nature give us a deeper understanding of the evolution and structure of the universe.
The discovery of black holes also allows us to cherish the future of the earth and humanity even more. The gravitational pull of a black hole is so strong that it can devour everything, including Earth and humans. Therefore, we need to work harder to explore the universe and find more resources and living space to ensure the future of humanity.
The discovery of black holes also makes us more in awe of the forces of nature and the universe. Black holes are one of the most powerful celestial bodies in the universe, and their existence and nature allow us to feel the infinite mystery and power of nature and the universe.
