This video is from an early version of Universe Sandbox ² and doesn’t represent the latest improvements.
Universe Sandbox ² is a powerful space and gravity simulator that lets you create and destroy on a scale you’ve never before imagined.
Realistically model our solar system or bend the laws of physics, speed up time and watch stars evolve till they supernova, manipulate Earth’s seasons or twist its orbit outward and freeze the oceans solid, then spawn a nearby galaxy to rip apart the Milky Way.
A complete rewrite of the original by a team that now includes an astronomer, a climate scientist, and a dedicated physics programmer, this sequel opens doors to more exploration and interaction.

Universe Sandbox ² is now available on Steam Early Access for PC, Mac, and Linux:
