What is Universe Sandbox ² ?
It merges gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.
Create, destroy, and interact on a scale you've never before imagined.
For Windows, Mac, and Linux.
What can you do with Universe Sandbox ² ?
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.
Add carbon dioxide to a planet's atmosphere to heat it up. Then add water...
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.
- Material System - build planets out of Hydrogen, Iron, Rock, & Water
- Solar flares & volatile trails
- Procedurally generated
stars and planets
- Light-warping black holes
- Dark matter

What Are People Saying About It?
It's easy to use, beautifully tutorialised, and hugely fascinating.
I just finished playing and my mind is blown. I spent most of my time staring at the screen, smiling like an idiot.
Who hasn't wanted to crash the Earth into the sun or bombard the moon until it's nothing but a pile of rubble?
Most epic moment - increased the mass of the sun when it suddenly flashed insanely in a giant supernova. Epic touch.
...a vast improvement over the original. ... an incredibly enjoyable simulator.
It's like my great grandfather always used to say, 'Nothing like destroying 45 simultaneous instances of the Milky Way to brighten up a bad day.'
Everyone should be playing Universe Sandbox ².
To describe the simulated destruction of Earth as satisfying is to undersell the delight of a child with a magnifying glass and some plastic soldiers.
I just love this stuff. I could explore this game all day.
Love this program. So pretty. You guys really outdid yourselves!!
If the water starts to evaporate, this might be one of the best games ever made... [water evaporates]
This game is so ******* cool.
A space simulator like no other: The Sims meets Elite meets Stephen Hawking's archives.
This simulator really puts you in the driver's seat to the universe we live in.
...the greatest science games of all time. You guys are doing incredible work and creating things I've never seen done before... You're all making something special.
