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. 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. And more... Material System - build planets out of Hydrogen, Iron, Rock, & Water Stellar flares & volatile trails Procedurally generated planets, stars, & galaxies Pulsars Light-warping black holes Original soundtrack by Macoubre Support for 20+ languages Officially supports the same Linux distributions as Proton.
