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

it's cool, but this game has been in early access for so long that i actualy gave up and forgot about it
it's kinda good i play it if i get bored, and its awesome for education
good
Graphics are awesome and there is a large variety of ways to play.
Pretty fun. You basically get to do anything from terraforming exoplanets, to colliding gas giants, and also remaking Miller's planet (Interstellar). I'd recommend it.
i like space i think its cool because you can make solar systems and many other things
its a good game but a little expensive but nice
. there is no reviewe 10/10 would delete the moon again
Realistic, fun, and would be great if they added more damage physics like craters but I understand because it would probably take a lot of work and might crash user's game if they do that.
muito bom teho 124 horas jogadas muito relaxante e satisfatorio e maneiro recomendo MUITO!!
