Three Body: Gravity Chaos · Coming Soon
Three bodies. One rule. No formula.
Two bodies orbit forever in a clean ellipse. Add a third and Newton's gravity becomes unsolvable in general. Three Body lets you watch the rare orbits that do repeat, and the many that never do, with glowing trails and a twin copy that shows chaos as it happens.
The orbits are real solutions from the research literature, simulated on your device. Chaotic runs are sensitive to tiny differences by nature, so exact outcomes can vary between devices and settings.
Explore
Watch it, bend it, map it.
Start with a named orbit, design your own by dragging bodies and flicking their velocity, or pick a point on the chaos map and see where it goes.
Real periodic orbits
The figure-eight, the Lagrange triangle, butterflies, moths and more, from published solutions.
Chaos twin
A copy of the orbit started a millionth away. Watch the gap stay flat, or explode.
Chaos map
Every launch speed colored by how chaotic it is. Zoom in and launch any point.
Daily Orbit
One new launch a day, the same for everyone, with a streak and an Atlas of things you have found.
Posters and video
Turn any orbit into a poster or a short clip, and share a seed so anyone can replay it exactly.
Calm mode
Hide every control and just watch. Optional Pro unlock adds every orbit, the deep map and more.
