The original Universe Sandbox was only available for Windows-based PCs, but an updated version was released for Windows, macOS, and Linux in 2015. Using Universe Sandbox, users can see the effects of gravity on objects in the universe and run scale simulations of the Solar System, various galaxies or other simulations, while at the same time interacting and maintaining control over gravity, time, and other objects in the universe, such as moons, planets, asteroids, comets, and black holes. Universe Sandbox is a series of interactive space sandbox gravity simulator educational software video games.
