Space Sandbox allows you to create your own universe populated with comets, planets, moons, gas giants, stars, and even black holes. Watch as the celestial bodies orbit each other and collide in fiery explosions. Design everything from simple solar systems to massive galaxies. Save your favorite universes and change them later.
