gravity simulator

science it a wonderful subject to learn by doing. throw a ball to learn how trajectories work, break open rocks to study minerals. but abstract topics, like theoretical physics, don't lend themselves to easy experiments. can you travel near the speed of light? (spoiler alert) no. no you cannot. but in a simulation, you can!

3d gravity simulator. simulate the solar system, exoplanets and even colliding galaxies. add, delete and modify planets, and change the laws of physics.
