Create and destroy on a scale you never before imagined.
Universe Sandbox ² is a space simulator that merges gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.
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 astrophysicist, a climate scientist, and a dedicated physics programmer, this sequel opens doors to greater power and exploration.
With the recent addition of support for the HTC Vive/SteamVR, you can fly around your simulation, melt planets with a giant laser, and hurl them around with a flick of the wrist.

Universe Sandbox began as Dan's personal project - a physics program that would make a nice portfolio addition. It wasn't long, however, before he realized the potential of this powerful gravity simulator: It didn't just appeal to computational physicists; it opened a door to understanding our complex universe. And besides, who doesn't want to smash Earth into Mars? Sure enough, it quickly became a Steam-success story.
Simulating the universe, however, is never a completed task. Universe Sandbox was a great tool for exploring (and destroying) the cosmos, but there were some things missing. What about comets? What about dark matter? Or how about the pressing issue of climate change?
The scope for the sequel meant that it could no longer be just a one-person project. In Fall 2011, Dan hired two additional developers and began creating from scratch Universe Sandbox ². Funded entirely by the sales from the original Universe Sandbox, the eight-person team now includes a dedicated physics programmer, an astrophysicist, and a climate scientist.
