A developer created an interactive solar system simulator called Gravity that demonstrates orbital mechanics from Newtonian physics to Einstein's general relativity. The educational tool features accurate orbital calculations, real planetary data, and includes features like gravity assists and spacetime curvature visualization. Built with TypeScript and Three.js, it runs entirely client-side and includes both simplified and accurate scale modes for better visualization.
Background
Orbital mechanics and gravity visualization tools are valuable for both education and scientific communication, helping to demonstrate complex physical concepts in an accessible way. The use of web technologies for scientific visualization has grown significantly, enabling interactive learning experiences directly in the browser.
