Gravity Simulator - Interactive Space Physics Sandbox In Your Browser

Hey Product Hunt 👋 I built Gravity Simulator to make gravity and orbital physics feel interactive instead of abstract. Most online physics simulations are either too limited, visually outdated, or locked behind heavy desktop software. I wanted to create something that runs entirely in the browser while still feeling immersive, responsive, and scientifically inspired. Gravity Simulator currently includes two interactive simulation engines: 🌍 Object Drop Engine: Test how gravity affects falling objects across planets and moons using different gravitational environments. 🪐 Orbital Gravity Simulator: Create and experiment with orbital systems, planetary motion, collisions, slingshots, and chaotic N-body interactions in real time. The goal was to blend education, experimentation, and visual simulation into a single accessible platform for students, educators, creators, and space enthusiasts. Some of the biggest challenges were balancing physics accuracy with browser performance, designing intuitive controls, and making the simulations feel visually cinematic while remaining interactive. I’d genuinely love feedback from the PH community: • What experiments would you want to try? • Which features would make this more useful or fun? • What celestial mechanics tools would you like to see next? Thanks for checking it out 🚀
