Is the environment of Trina System really as horrible as that described in Three-body? Is there no rule to follow?

The trilogy "The Past of the Earth" (Three-body, Three-body Ⅱ Dark Forest, Three-body Ⅲ Death and Eternal Life), also known as "Three-body" trilogy, is the first series of works by China famous science fiction writer Liu, which was planned and produced by Science Fiction World magazine and published by Chongqing Publishing Group. The novel tells the story of the three-body world's invasion of the earth caused by an accidental interstellar communication in the Govern period, and the feud between human civilization and three-body civilization for more than 300 years. After the publication of The Trilogy of the Past of the Earth, it sold well and was well received by readers and mainstream media. It is widely regarded as a milestone in China's science fiction literature, which has set a new height for China's science fiction.

The three-body world is a world with extremely harsh living environment that the earth people can't imagine at all. There are three "suns" with similar mass in the three-body world. According to Newton's law of motion, the trajectories of these three suns are completely unpredictable (three-body problem). The planet where the three people live is influenced by the gravity of three suns, which leads to the abnormal orbit of the planet. When the planet is captured by a sun and rotates around it, the three people will temporarily get a stable development period, which is called "eternal era" by the three people. When the planet is not captured by a sun, and the sun rises and sets irregularly, this period is called "chaos era". To this end, the three-body people evolved the instinct of dehydration in the chaotic times to deal with the crisis. But this is not always effective, because the three suns run irregularly, and when the planet is too close to the sun, the surface will melt because of the high temperature; When it is too far away from the sun, the temperature will be too low; What is even more frightening is that when the planet approaches several suns at the same time, the stars will split because of the tearing of gravity. Three-body civilization has been destroyed hundreds of times for the above reasons. But what is particularly frightening is that because the mass of the planet is too small relative to the sun, it will eventually fall into the sun because of the chaotic orbit, so that the three-person and the three-person civilization will disappear forever. For three people, space migration is the only choice. The three-body society is always facing the crisis of destruction, so it has evolved a highly totalitarian social system and values completely different from the moral culture of the earth, because only in this way can it survive.

After "Three-body 1", I wondered what else the author could write. I didn't expect him to write Dark Forest. Now, after reading "Dark Forest", I really can't think of anything new that the author can write in the third "Forever Death"! ! !

Fortunately, I am still a utilitarian, and now I can feel the feeling of being reluctant to sleep more and more.

By the way, the star closest to the sun? This is Alpha Centauri, and this is a triad:

Alpha Centauri A: It has the same chemical composition as the sun and the same brightness (0 magnitude). China's astronomy is called Nanmen geocentric theory.

Alpha Centauri B: This star is the companion of Alpha Centauri A, with a magnitude of+1.33 and a distance of 13.8 arc seconds. The two stars revolve around each other in an eight-year cycle. China is called Nanmen Eryb in astronomy.

The main star, Alpha Centauri C: Also known as proxima centauri, is the third position of this star. It is the closest star (4.2 light years) to the sun at 2 degrees southwest of the earth, and it is a red dwarf with brightness of+12.4. China is called Nanmen Erc star in astronomy.

"Three-body" is a science fiction masterpiece of Liu, which tells the story of the struggle between the earth people and a ternary star system civilization, and the final outcome is the destruction of the solar system and the three-body galaxy.

In the novel, the environment of triple star system civilization is described as creepy. The three stars there run completely irregularly, causing the planetary civilization there to suddenly fall into extreme cold and freeze to death without warning, and then suddenly exposed to hot flames, with no rules to follow.

But there is an incredible civilization that is more advanced than the earth.

In fact, the three-body science fiction novel Three-body is based on the real trinity system in the universe. This three-body 4 light-years away from us comes from Alpha Centauri.

This triple star system, also known as Nanmener, is less than 4.3 light years away from us and consists of three stars, A, B and C, in Nanmener. Among them, the two stars A and B are a binary star system, rotating around an empty particle, and they are also the larger two stars in the three-star system.

Nanmen2a is a yellow dwarf star similar to the sun, and its mass is about 1. 1 times that of the sun. Star B is an orange dwarf star with a mass slightly less than that of the sun, about 0.9 times that of the sun.

Nanmener C star, commonly known as proxima centauri, is the nearest star at present, about 4.22 light years away. It is a very small star in this triad galaxy. It is a red dwarf, and its mass is about 1/8 of that of the sun. This star is a little farther from the main binary star, about 15000 astronomical units. It rotates around this binary system, and it takes about 500,000 years to make one turn.

It is found that both star B and star C in the three-star system are accompanied by planets, namely South Gate Bb and neighboring star B..

Planet B, the neighbor of Star C, is a planet located in the livable zone, and its mass is 1.3 times that of the Earth. However, due to the characteristics of red dwarfs and the close distance between planets (only 7 million kilometers), the possibility of life is very small, let alone civilization.

Nanmener Bb is close to the main star, only 0.04 astronomical unit, that is, 6 million kilometers, and its mass is about 1. 13 times that of the earth, and period of revolution has 3.2 Earth days. Nanmener B is a star much bigger than proxima centauri. Being so close to it is equivalent to being in the high-temperature corona of the sun, like a burnt potato. Therefore, according to the current scientific cognition, it is completely unsuitable for the reproduction of life and civilization.

If you look at the sky on the planet of Nanmen, it is not as chaotic and horrible as described in Three-body.
