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.

Highlights

• Simulate gravity: N-body simulation at nearly any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
• Collision between Planets and Stars: Epic, mind-blowing collisions of massive planetary bodies leaving behind molten craters.
• Create your own systems: Start with a star, then add a planet. Introduce moons, rings, comets, or even a black hole.
• Model Earth's Climate: Watch sea ice grow and recede with the seasons due to Earth's tilt: change the tilt and alter the seasons. Or move Earth further from the Sun and freeze the entire planet. Learn more...
• "Supernova" a Star: Have a star evolve by increasing its age or mass, then watch a supernova unfold.
• Explore historical events: Ride along with the Juno and New Horizons spacecraft, or witness a total solar eclipse.
