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

good
W game I used to watch this game like 8 years ago when I was like 5 and I wished i had it
I loved and cherished about the game’s graphics, topics, objects, movements and gameplay.
无穷的宇宙。神创造了一颗星球，然后是第二颗和第三颗。它们碰撞着，毁灭着，又形成新的秩序。神很开心，肆意摧毁和创造着。祂以为这是一个叫《宇宙沙盒》的模拟游戏，但不幸的是我们生活在这个宇宙，地球在祂降临一刹那后就该毁灭了。不过好在祂太卡了换了个宇宙玩，地球逃过一劫。 ——公元1145141919810年
this game is good
If you are creative and like astronomy, this is the game for you.
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.
