Universe Sandbox ²





Universe Sandbox ² is a physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.

It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet. Universe Sandbox ² is the long awaited sequel to the original Universe Sandbox.

Universe Sandbox ² includes the desktop version and a new VR mode with support for the HTC Vive. This is a free, automatic update.

Simulate Gravity

N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.

Collide Planets & Stars

Epic, mind blowing collisions of massive planetary bodies.

Model Earth’s Climate

Watch sea ice grow and recede with the seasons because of the tilt of the Earth: change the tilt and change the seasons. Or move the Earth farther from the Sun and freeze the entire planet.

Terraform Planets

Add carbon dioxide to a planet’s atmosphere to heat it up. Then add water…

Deform Surfaces

Impact planets with asteroids and comets and leave behind massive, molten craters.

Supernova a Star

Make a star evolve by cranking up its age or mass, then watch a supernova unfold.

And more…

  • Material System – build planets out of Hydrogen, Iron, Rock, & Water
  • Solar flares & volatile trails
  • Procedurally generated stars & planets
  • Pulsars
  • Light-warping black holes
  • Dark matter
