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

11 years later and its still in "early access"
really good, I would say that there is some quirky bugs sometimes and sometimes they're funny, and sometimes they ruin everything, but the handy debug tool is here, so yeah, good but a bit unpredictable
it actually is very important to know the Schwarzschild Radius of a baseball

O Universe Sandbox é um dos simuladores espaciais mais impressionantes disponíveis na Steam. O jogo permite criar, destruir e modificar sistemas planetários inteiros de forma extremamente realista, utilizando leis reais da física e da gravidade. Um dos maiores pontos positivos é a liberdade que o jogador possui. É possível recriar o Sistema Solar, criar planetas personalizados, simular colisões entre mundos, testar cenários científicos e observar os resultados em tempo real. Tudo isso com gráficos bonitos e uma interface relativamente fácil de aprender. Além do entretenimento, o jogo também possui um grande valor educativo. Ele ajuda a compreender conceitos de astronomia, órbitas, gravidade, temperatura e formação de sistemas planetários de maneira prática e divertida. Para estudantes, professores ou simplesmente curiosos sobre o universo, a experiência é extremamente enriquecedora. Outro destaque é a constante atualização feita pelos desenvolvedores, que continuam adicionando melhorias, novos recursos e refinamentos ao longo dos anos, mantendo o jogo moderno e Nota: 9,5/10 ⭐

DAS Sandbox Spiel schlechthin. Wer auch nur etwas Interesse am Cosmos hat und gerne bisschen herumspielt muss Universe Sandbox kaufen. Atemberaubend. Kinderleicht. Passionierte Devs.
