Universe Sandbox

About the game

A closer look.

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. Simulate Gravity N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required. 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. 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. And more... Build and terraform planets with 12 materials, including water, oxygen, & carbon dioxide Stellar flares & volatile trails Procedurally generated planets, stars, & galaxies Pulsars Light-warping black holes Epic space lasers Shape oceans & mountains on planet surfaces Spin planets apart with centrifugal force Original soundtrack by Macoubre Support for 20+ languages Share & explore simulations on Steam Workshop
