About The Game
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 GravityN-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Collide Planets & StarsEpic, mind blowing collisions of massive planetary bodies that leave behind molten craters.
Create Your Own SystemsStart with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.
Model Planetary ClimateWatch 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 StarWatch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.
Explore Historical EventsHitch 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
