About
Universe Sandbox is a realistic 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.
N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.
Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.
Watch sea ice grow and recede with the seasons because of a planet’s tilt - change the tilt and change the seasons. Or move planets close to a star and see the oceans boil away as the surface heats up.
Watch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.
Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.
Build and terraform planets with 12 materials, including water, oxygen, & carbon dioxide
Stellar flares & volatile trails
Procedurally generated planets, stars, & galaxies
Pulsars
Light-warping black holes
Epic space lasers
Shape oceans & mountains on planet surfaces
Spin planets apart with centrifugal force
Original soundtrack by Macoubre
Support for 20+ languages

This is boring. Took me a long time to figure out the basics. DO NOT PLAY
Es el mejor juego que he probado enserio creanme, tengo la mejor pc se los prometo miren mis componentes
This game has 2 kinds of players: Those who spend thousands of hours completely infatuated with the universe and thier godlike power within it. And those who get bored within 30 minutes after they sucked everything into a blackhole for the 10th consecutive time. I was the the latter.
This game is awesome if you like worldbuilding (literally). Also, it's good if you like [strike]destruction[/strike] fun. Either one.
for the people who are interested in space and the universe, etc.
My son is autictic. HE loves space. This game is a dream come true for him, he can fly though the universe and visit all its wonders. Thank you dev for all your hard work.
The best space god simulator I ever played!
I ABSOLUTELY LOVE THIS GAME 10/10!!! WOULD RECOMMEND!!!
The game is awesome! It's creative and lets you expirement. Plus, it's only a 1 time payment!
