Does "Three-body" really exist? What about the "six bodies"?

The three-body civilization in Three-body doesn't necessarily exist, but the universe is so big that we can't deny the existence of other alien civilizations. Science fiction is about the future, and we can't confirm what kind of civilization will appear in the future. However, the discussion of human nature in Three-body is of practical significance. As for what the three-body civilization looks like, there is not much ink in the book. What we can know from the book is that three people can communicate without talking, and the technology is far above the earth. Even we don't know what the trio looks like.

Liu Zeng wrote in Time Migration: "Science fiction is a macro narrative and a cosmic aesthetics on a light-year scale." The universe is big, but the human heart is bigger. In fact, Liu's "Three-body" pays more attention to the consideration of human nature than the real face of the three-body world. Instead of looking forward to an illusory future, it is better to do a good job in the present.

Liu Zeng said that the reference object of the three-body world comes from Alpha Centauri, because Alpha Centauri is just composed of three stars, which coincides with three irregular "suns" in the three-body world, but the latest research shows that this statement may be wrong, which means that this planet may not exist at all. The prototype of Liu's three-body world probably does not exist, so the three-body world does not exist.

But there may be three-body motion in the universe.

Because of the more complicated operation rules of the three stars, the "constant era" and "chaotic era" appeared alternately in the three-body galaxy, which led to the destruction of the three-body civilization by the terrible disasters caused by the three stars many times. Every civilization in the three-body galaxy will be destroyed by various doomsday disasters caused by Trinary star system after it has developed to a certain period.

Because the gravity in a single star system is relatively simple, the celestial body will run regularly; In the binary system, the gravitational interference of the planets in the star system will be quite serious. Although the "livable zone" can also be found in the binary system, and liquid water can exist on the surface of the planet, it is often difficult for life to adapt to such extreme environment, because the orbit of the planet cannot always be in the livable zone.
