Universe Sandbox (formerly 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 is the long awaited sequel to the original Universe Sandbox Legacy.
- 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.
- 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.
- Terraform Planets
Add carbon dioxide to a planet's atmosphere to heat it up. Then add water...
- Deform Surfaces
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.
- And more...
- Material System - build planets out of Hydrogen, Iron, Rock, & Water
- Solar flares & volatile trails
- Procedurally generated stars & planets
- Light-warping black holes
- Dark matter
