What if a person falls into a black hole?

The world's largest scientific instrument, the large Large Hadron ordinator, was officially launched in Switzerland on the 10th. Some people worry that this particle accelerator will eventually cause the whole world to be swallowed up by black holes, especially when it runs at the highest energy next spring. Scientists say this worry is superfluous, but if you really fall into the black hole, what will happen?

In his book, Neil digeras Tyson, director of the US Natural History Museum, described the consequences of falling into the black hole. He said that once it falls into the black hole, your body will be torn into small fragments. And he thinks this is "the most spectacular method of death in Space ".

Black hole is a place where gravity is very powerful. You must run faster than light to escape its drag and drop. Because nothing in the universe is faster than light, it is impossible to think of anything as soon as it falls into the black hole. The gravity of the black hole boundary has become exceptionally powerful, so this region has produced the well-known "Event Horizon" phenomenon. The "black hole surface" is the border of a black hole. It was not until 1940s that some scientists believed that material had accumulated on the "black hole surface" and would not collapse.

The closer the black hole center is, the stronger the gravity. If you are sucked by the gravity of the black hole, you will jump into the center with the free falling motion. As you get closer and closer to the black hole center, traction will become stronger and stronger, and this result will generate a so-called "tidal force" in your body ". That is to say, the gravity on your head is more powerful than the gravity on your toes, so you will jump into the black hole. Gravity leads to faster head acceleration than toe acceleration, which will stretch your body until it is torn into fragments.

The most vulnerable joints in the body are torn apart. As the "tidal force" becomes stronger than the chemical bond that connects the body together, the whole body is torn apart. In the end, you will become unrelated atoms. These atoms are arranged in a straight line and continue to run forward. As Tyson described, you will be "squeezing toothpaste from a tube and passing through space ." No one knows what happens when the atoms arrive at the black hole center.

In a small black hole, predicted by the doomsday commentator of the large-scale Hadron orlinder, such decomposition would happen instantly. As a matter of fact, this process will happen before you have crossed the "black hole surface". The entire decomposition process is no more than one million seconds. The more material and people a black hole swallowed up, the larger it will become. As the body size increases, the severity of the black hole decreases slightly.

As the volume of the black hole increases, the internal gravity difference becomes less obvious. If you fall into a giant black hole, before you pass through the black hole surface, the change rate of gravity and the influence of the tidal force may not be enough to tear you apart. If you fall into a black hole that is large enough, you will feel a bit like a distorted single-phase mirror at the last moment. People outside of the world cannot see you, but you can see them. In this period, gravity will change the direction of the light, and finally let you slowly deform. (Xiaowen)
