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

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

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

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.

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

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