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

Words cannot describe what this game is to me - this is the 1st game I got when I got Steam back in 2016 and the game has changed so much its a nice taste of it all. Nostalgic for the past and still good that its making new funs and glory for destruction and peace and utter beauty. Love the game to my core.
Very good simulation but it is limited to your imagination. I personally lack enough creativity to enjoy this game. This [b]IS[/b] a sandbox so if you don't do well with sandbox games, I wouldn't recommended it. But I know a lot of people do so I will recommended this game
This game is just the best. I terraformed Mars, destroyed the Earth and killed everybody :) Good game
要是能加个 里面可以产生人,然后控制人发射火箭等之类的 到其他星球就好了
本人小学的时候天天在爱奇艺优酷上面看二代宇宙沙盒的实况,当时玩的是初代宇宙沙盒,引擎与精细度都一般,用的是十几年前的华硕笔电,根本带不动二代的宇宙沙盒,上高中换了台电,今年夏促突然想起来这款游戏,遂购入。终于圆梦了。 等钱攒够了我还会去买Space Engine的。
Universe Sandbox один из лучших симуляторов космоса вообще из когда либо созданных и это одна из первых игр которые я купил себе на аккаунт в далеком 2015 году. Очень печалит что с тех пор у игры очень маленькие продажи, потому что игра однозначно заслуживает лучшего. Здесь можно творить буквально все о чем я в детстве мечтал, взорвать спутники Юпитера? Пожалуйста. Запульнуть комету или что побольше на Марс и посмотреть что будет? Да запросто. Причем игра не ограничивается просто солнечной системой, есть и экзопланеты и черные дыры и чего тут только на самом деле нету. Думаю что однозначно рекомендую к ознакомлению.
It's really good for showing people the scale of cosmic objects e.g. Betelgeuse next to our Sun.

Such a fun space sandbox game, I love making my own solar systems and chaotic orbits and life on planets. Cant wait for the life update.
# The Weight of Creation: Universe Sandbox Most games ask you to survive in a world. Universe Sandbox asks something far more unsettling: What happens when the world survives because of you? At first, curiosity takes over. You move planets. Change orbits. Create stars where none existed before. You experiment with gravity as if it were a toy. Then Earth disappears. A collision you didn't expect. A moon placed too close. A star made slightly too large. An entire world erased in seconds. And suddenly, the scale of what you're looking at becomes impossible to ignore. Every planet is a delicate balance. Every orbit is a silent agreement between gravity and time. Every stable system is the result of countless forces working together across millions of years. The universe feels eternal until you are given the power to break it. That's what makes Universe Sandbox so fascinating. It transforms physics from a collection of equations into something you can feel. You don't just learn how worlds are created. You learn how easily they can disappear. There is something strangely humbling about watching a civilization's home vanish because of a decision you made with a single click. Not because it is destructive. But because it reminds you how fragile existence truly is. Universe Sandbox is often described as a physics simulator. For me, it felt more like a lesson in perspective. A reminder that every world is a miracle. And miracles are far easier to destroy than they are to create.
