Universe Sandbox 2 is a full rewrite of the original Universe Sandbox for Windows, Mac, and Linux. In development since late 2011, we are working hard to make the new version more amazing than the original in every way. We can’t wait to release it to everyone, but won’t release it until it’s ready.

The new Universe Sandbox is a way of learning about our amazing universe and fragile planet via a powerful gravity simulator and an expanding realm of realistic and interconnected astronomy and climate physics systems.
