What terrible things will happen when black holes collide? Can you tell me?

Black holes are the most mysterious celestial bodies in the universe. What happens if two black holes happen to meet and collide? What happens when two black holes collide? A black hole is a high-density area in space, where the gravity is so strong that nothing can escape its gravity, even light.

So far, scientists have identified different types of black holes, including supermassive, medium-sized and miniature black holes. Stellar black holes are everywhere in the universe, and there are billions of black holes in the Milky Way alone. One of the characteristics of black holes is that they can move freely in the universe. Because of this, they are always likely to bump into each other. If such an event happens, it is obvious that the result will be devastating. What will happen if two black holes collide depends on the size and speed of the two black holes, their rotation speed and the angle of collision. For example, if these ultra-high-speed rotating black holes collide with each other at right angles, small black holes will be hit by big black holes and small black holes will fall into space uncontrollably. But if not, the most likely result will be that they can't escape each other's gravity and get closer and closer until they start to rotate around each other. In this process, they began to pull matter and gas into the whirlpool between them. In the next few billion years, they will eventually merge with each other to form a new and larger black hole, which is called a binary black hole.

In fact, this is not as simple as it sounds. This is because when two black holes collide in this way, the energy released by this collision will be so powerful that it will cause ripples in the universe in the form of gravitational waves. These energy waves contain eight times the energy of our sun. This energy is equivalent to launching 100 trillion atomic bombs per second, lasting 654.38+03.8 billion years. Therefore, if such a collision occurs anywhere near the solar system, the energy from these merged black holes will destroy everything in their path, including the earth. Fortunately, this is unlikely to happen, because the nearest black hole is called a unicorn, which is about 1500 light-years away from the earth. This is a very, very long distance, you know? On May 2, 2009, 2065438+Kloc-0/day, the earth trembled because of the gravitational waves generated by the collision of two massive black holes nearly 7 billion years ago. Researchers estimate that these two black holes are 66 times and 85 times the mass of the sun, respectively, and these two black holes merge to form a black hole with a mass 142 times larger than our sun.
