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 ² is the long awaited sequel to the original Universe Sandbox.
Simulate GravityN-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Collide Planets & StarsEpic, mind blowing collisions of massive planetary bodies.
Model Earth's ClimateWatch sea ice grow and recede with the seasons because of the tilt of the Earth: change the tilt and change the seasons. Or move the Earth farther from the Sun and freeze the entire planet.
Terraform PlanetsAdd carbon dioxide to a planet's atmosphere to heat it up. Then add water...
Deform SurfacesImpact planets with asteroids and comets and leave behind massive, molten craters.
Supernova a StarMake a star evolve by cranking up its age or mass, then watch a supernova unfold.
