Gravity – Interactive solar-system simulator, from Newton to Einstein

This interactive solar-system simulator, built for self-education, visually demonstrates the physics of orbital mechanics from Newtonian gravity to Einstein's relativity. It is designed for curious learners who want to understand *why* orbits exist, not just observe them, by offering a step-by-step guided tour starting with two bodies and time. The project is interesting because it fills a gap in traditional education, making abstract gravitational concepts tangible and intuitive through hands-on exploration.
