Universe Sandbox

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. Universe Sandbox includes the desktop version and a VR mode with support for the HTC Vive, Oculus Rift+Touch, and Windows Mixed Reality.

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. Learn more... 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. Throw Planets in VR Just grab and fling. And more...
