The three-body problem stumped Isaac Newton and Henri Poincaré—the latter even laying the groundwork for chaos theory while trying to solve it. A major breakthrough came in 2000, when Alain Chenciner and Richard Montgomery uncovered the famous figure-8 solution—shown in clip 4. In 2013, Milan Šuvakov and Vladimir Dmitrašinović expanded the picture further, identifying 13 additional families of solutions. Each clip represents a true numerical integration of Newton’s law of gravitation, F = G·m₁m₂/r², using equal masses—no tricks, no shortcuts. It’s a reminder that mathematics dating back to 1687 still holds deep and unexpected surprises. [🎞️ extract: From Infinity with Love]
