Universe Sandbox ² 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 ² is the long awaited sequel to the original Universe Sandbox.
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.
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.
Add carbon dioxide to a planet's atmosphere to heat it up. Then add water...
Impact planets with asteroids and comets and leave behind massive, molten craters.
Supernova a Star
Make a star evolve by cranking up its age or mass, then watch a supernova unfold.
- Material System - build planets out of Hydrogen, Iron, Rock, & Water
- Solar flares & volatile trails
- Procedurally generated stars & planets
- Light-warping black holes
- Dark matter
