Three Body Problem: Gravity

See the real three-body problem in motion.

Three bodies, one gravitational field, and no way to predict what happens next - this is the actual physics behind the famous unsolvable problem (and the novel/show that made it famous). Drop in two, three, five bodies and watch orbits that look stable... until they don't.

This is a real gravity simulator, not just a visual. Choose Newtonian, simplified relativistic, or simple orbital physics. Pick your numerical integrator (fast Euler or precise Runge-Kutta 4). Tune gravity strength, softening, collisions, and more.

FEATURES

- Real orbital mechanics: Newtonian gravity, relativistic corrections, multiple integrators

- Watch chaos emerge from simple rules - tiny changes in starting position lead to wildly different outcomes

- Smooth, glowing, hypnotic to watch

- Fully offline, no account, no ads, no tracking

- Free

Whether you're curious about the real science after the book or show, studying chaos theory, or just want something oddly satisfying to stare at - this is orbital chaos you can actually play with.
