Do threesomes really exist?

Because now human beings can't observe the situation of Centauri star system through astronomy, it is known that there are three stars in Centauri doing three-body motion, but now human beings have no solution to the study of three-body motion, so they don't know whether the environment of their star system is stable, so they can't judge whether there is life. The environment of the Centauri galaxy set by Liu is unstable in the three-body system, so the three-body civilization has evolved dehydration ability.

The three-body world means that a galaxy has three suns. At present, mankind has discovered such a world, that is, proxima centauri of Alpha Centauri. However, compared with the chaotic trajectory of the three-body world in the book, the three-body system of Alpha Centauri is almost always in a stable state.

Because proxima centauri is very far away from the other two stars, and proxima centauri is much smaller in size and mass than the other two stars, which are very close to the sun. If proxima centauri is also the size of the sun, the distance between the three stars will decrease due to the increase of gravity. Narrowing down to a certain range, three stars form a real three-body system.

Three-body galaxies in the universe;

The solar system is a single-line system, because there is only one star, the sun. In fact, the vast majority of galaxies in the universe do not appear in the structure of the solar system, but are binary systems. The triad system in the three-body world also exists in the universe, which is called triad system. It has such a special galaxy, about 1300 light-years away from the solar system.
