About 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.
Universe Sandbox includes the desktop version and a VR mode with support for the HTC Vive, Oculus Rift+Touch, and Windows Mixed Reality.

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.

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