Universe Sandbox 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.
Features
- 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 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.
- Supernova a Star: Make a star evolve by cranking up its age or mass, then watch a supernova unfold.
- Explore Historical Events: Ride along with the Juno and New Horizons spacecraft, or view a total solar eclipse.
