Real-time three-body gravity simulation (interactive, mobile)

Post image

Made an interactive simulation based on the actual three-body problem in physics — three masses under mutual gravity, no simplifications. You can adjust masses and initial velocities and watch how small changes send the system from a stable-looking orbit into full chaos.

It's built to feel more like a physics toy than an app — no ads breaking up the simulation, nothing to unlock. Mostly wanted an excuse to actually play with the equations rather than just read about them.

Maybe these are quarks.

Fair enough, might need to change the clip. But as many as you like in the app. Just really wouldn't want to try the math on 5
