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 Gravity

N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.

Many small objects chaotically orbiting a planet, which orbits a star.

Collide Planets & Stars

Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.

The Moon colliding with Earth showing a large impact.

Create Your Own Systems

Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.

Adding a star to a simulating using the Add menu, part of the user interface.

Model Earth's Climate

Watch 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. Learn More... (Opens in new tab)

Earth is completely frozen over next to a terraformed Mars, which is next to an Earth with no water.
