Universe Sandbox is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.
It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. Universe Sandbox is the long awaited sequel to the original Universe Sandbox.
Simulate Gravity - N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics.
Collide Planets & Stars - Epic, mind blowing collisions of massive planetary bodies.
