Universe Sandbox ² [Online Game Code]

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
