What can you do with Universe Sandbox ?
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.
Create Your Own Systems
Start with a star then add planets. Spruce it up with moons, rings, comets, or even a black hole.
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.
Supernova a Star
Make a star evolve by cranking up its age or mass, then watch a supernova unfold.
Explore Historical Events
Ride along with the Juno and New Horizons spacecraft, or view a total solar eclipse.
And more...
- Material system:
build planets out of hydrogen, iron, rock,
& water - Stellar flares & volatile trails

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.
[Universe Sandbox] is one of the coolest things I've used on Vive so far.
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.
This simulator will blow your mind. I love it.
Everyone should be playing Universe Sandbox.
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!!
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.'
If the water starts to evaporate, this might be one of the best games ever made... [water evaporates]
Space 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.
