About this project
A full-screen N-body gravity simulator — click to place planets, stars, and black holes, drag to launch them, then watch real orbital mechanics unfold with glowing trails. Six body types, three collision models, curated presets (figure-eight, galaxy collision) and a live energy/center-of-mass HUD.
