    This is one of those headlines that’s more obscuring than enlightening. We knew a bunch of ways that you could arrange three gravitational bodies and have them be in a stable orbit around each other. This adds 12,000 more. However, a general solution is still incredibly complicated, and the Trisolarans would still like to have a little chat with us in Australia some time.

    Title is wrong. Unsolvable means no general closed form solution. That doesn’t mean that single constellations cannot be proven stable.

    There is for example a trivial solution to the n-body problem. Arrange all bodies equidistant on a circle and have them move at the speed that keeps them on the circle.

    Damn it, I just started Cixin’s book and now these jerks are going to spoil it;)

        I thought the first book was pretty meh with big ideas but mid execution, but holy hell was the sequel exciting and leagues ahead in terms of quality. Really delivers on what the first novel sets up.

        Idk it was fun for me. I thought it was interesting being from China, I’m not that well read so the Chinese author put a cool perspective on the novel.

        I think it’s similar to a lot of golden age SF novels from Clarke, Asimov, etc. Big, fantastic ideas combined with characters that are cardboard cutouts.

      You clicked the thread!

      And me too, I’m just at the beginning of the second book lol

    Isn’t this already solved by total gravitational mass anyway? I’m not understanding what this article even means. You have 3 bodies that are constantly losing mass, and any difference in equilibrium means they fall out of orbit with each other. 3 bodies of exactly or near the density would decay at the same rate. I’m a laymen, but help me out here.
