Universe Sandbox

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.

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 that leave behind molten craters.

Create Your Own SystemsStart with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.

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.
