Universe Sandbox

Free Download Universe Sandbox 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 our universe's beauty and the planet's fragility.

Overview of Universe Sandbox

Universe Sandbox is a realistic physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.

Create & destroy on an unimaginable scale with a realistic physics-based space simulator. Explore the beauty of our universe and the fragility of our planet. Use science to bend the laws of gravity, collide planets, boil away oceans, fire epic space lasers, and customize your universe. VR optional.

Universe Sandbox Gameplay

Simulate Gravity

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

Collide Planets & Stars

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

Create Your Systems

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

Model Planetary Climate

Watch sea ice grow and recede with the seasons because of a planet’s tilt - change the tilt and change the seasons. Or move planets close to a star and see the oceans boil away as the surface heats up.

Supernova a Star

Watch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.

Explore Historical Events

Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.
