Work on Universe Sandbox began in fall of 2011 and it continues today by a growing team of talented developers, artists, and scientists. It merges real-time gravity, climate, collision, and physical interactions to reveal the beauty of our universe and the fragility of our planet. Universe Sandbox is a physics-based space simulator that allows you to create and destroy on an unimaginable scale while exploring the cosmos.
