Black holes can also be the home of life! Is there any scientific basis for this statement?

A world full of water, atmosphere and land, plus a star as stable as the sun, is an ideal home for life in the universe.

With the understanding of cosmic objects, there are more and more possible habitats for life. Life can live not only near yellow dwarfs like the sun, but also near red giants and white dwarfs.

And there is a potential habitat for life in the universe-near the black hole!

Although black holes are "black", they are not "cold"! Black holes are completely unattractive to life. As a giant gravitational monster, anything near the event horizon of a black hole will be pulled into spaghetti. If swallowed by black holes, you may not be able to escape them until the day when the universe is destroyed.

Nothing in the universe can escape from a black hole, even light, which makes the black hole without light. Compared with stars, black holes are very selfish and unwilling to share even a little light, but on the other hand, the gravity of black holes provides extra surprises.

The most powerful radiation in the universe is the cosmic microwave background (CMB), which permeates almost the whole universe and can easily drown the radiation of stars and even galaxies.

As radiation, CMB has a temperature, the absolute zero is -273. 15℃, and the temperature of CMB is about -270℃, which is too cold for life. However, when these radiations enter the black hole, the strong gravity will cause them to collide with a lot of energy, and the microwave frequency will gradually shift to red, and infrared rays or even ultraviolet rays will appear near the black hole.

The closer CMB is to the black hole, the higher the temperature will be, and it will reach a very high temperature before reaching the horizon of the black hole.

Black holes are potential life homes in the universe! If we fall into a black hole, we will not be frozen into ice near the black hole, but we will feel very warm; If a planet is close to a black hole, the ice on the planet will gradually melt into liquid water and become the home of life.

More importantly, the rotation speed of the black hole is very fast. The strong gravity and rapid rotation will make the infrared and ultraviolet rays converted by CMB gather into a beam, and the overall effect is very similar to that of a star.

Planets close to black holes will be affected by gravity and expand their horizons. Although the infrared converted by CMB is a light beam, it can cover a very wide area. If an earth-sized planet is near a black hole, about 40% of its surface will be illuminated. If the planet rotates, then the planet can also get a complete day and night.

But in the orbit of a warm enough black hole, the situation of the planet will be very dangerous. Maybe one day, when you wake up, you will find that the whole planet has fallen into a black hole. In order to keep the balance between the black hole and the planet, the revolution speed of the planet needs to be close to the speed of light!

Planets near black holes enjoy different times! The bigger the black hole, the more habitable space it provides, and the smaller the black hole, the more dangerous it is to life. However, the planet is too close to the black hole, and the revolution speed is close to the speed of light, which will lead to the expansion of the time system of the planet.

The planet near the black hole has passed 1 second, and the outside world may have experienced several days or even years; The planet near the black hole gave birth to the first generation of life, and the outside world may start to travel around by spaceship ~

Black holes can indeed be a potential home for life, but they will also have a serious impact on life.

If the earth is the prison of the universe, then the black hole can be called the "death prison" of the universe. Due to the expansion of time, the development speed of life will be very slow relative to the outside world. Any change in the planet may cause the balance to collapse and be directly swallowed up by the black hole.

It is almost impossible for life near a black hole to explore outer space. Unless the superluminal aircraft can be developed by using black holes, it is difficult to escape from the gravitational range of black holes. Even if other life finds life near a black hole, it is impossible to venture close to it. If you waste too much time near the black hole, you may never return to the original world (the time expansion near the black hole, 1 hour may be equal to a few years outside).

Humans now live near yellow dwarfs; In the future, the sun will die and expand into a red giant, and humans can also live near the red giant; After the red giant collapses into a white dwarf, humans can get enough energy as long as they are very close to the white dwarf.

When all the stars in the universe die and enter the black hole period, life may only risk living near supermassive black holes. Living near a black hole, the time left by the universe will be greatly extended. Perhaps life can join hands and enter other parallel universes suitable for life!
