About this game

Ever wondered what would happen if Jupiter slammed into the Sun?
Or what our galaxy will look like when it crashes into Andromeda?
Milky Way is the cosmic sandbox where you stop wondering and start
playing. Smash planets, merge galaxies, build solar systems, and
pick up real science along the way.

If you like Solar Smash, Universe Sandbox, Spaceflight Simulator,
or Solar System Sim, this is your next favorite app.

No lectures. No textbooks. Just gravity, collisions, and "what if?"
experiments you run with your fingers.

GRAVITY SANDBOX
Drop in planets, stars, and black holes. Real Newton's-law gravity
takes over. Build stable orbits, send moons flying, or kick off
total chaos. Every planet in the Solar System is here — Earth, Mars,
Jupiter, Saturn, even Pluto.

GALAXY MERGER
Crash the Milky Way into Andromeda. Watch supermassive black holes
fling stars across space. This is the same kind of simulation
astronomers use to model what will actually happen to our galaxy
in 4 billion years.

PROTOPLANETS (3D)
See how planets are born. Run a protoplanetary disk simulation and
watch dust clumps grow into rocky worlds and gas giants — millions
of years compressed into seconds.

SPH SIMULATION (PREVIEW)
Smoothed Particle Hydrodynamics, the technique real astrophysicists
use. Try the Three-Body Problem. Trigger Tidal Disruption when a
star wanders too close to a black hole. Watch math turn into a
fireworks show.

PLANET RIVALS
A fast game mode where you compete with other planets to grow into
the biggest world in the Solar System.

STELLAR COLLISIONS
Smash stars together. Trigger a supernova. Form a neutron star or
a black hole. All the violent cosmic events you'll never see with
a telescope, now in your hands.

MECHAZILLA CATCH
A SpaceX-inspired mini-game. Fire the Raptor engines on the Super
Heavy booster and help Mechazilla make the chopstick catch.

SOLAR SYSTEM COMPARISON
Put Earth next to Jupiter. Compare the Sun to Betelgeuse. Get a real
feel for how big the universe actually is.

WHY PEOPLE LOVE IT
- Real physics that doesn't feel like homework

evolution, black holes, and more
- Endless replay — every simulation runs differently
- Loved by space fans, students, teachers, and curious kids 9 and up

Rated 4.8 stars by 1,300+ space fans.

Ratings and reviews

this game is fun but for some reason I can't restart the game in cosmic rivals it annoying and I have a idea add upgrades to cosmic rivals and add a sandbox where you can spawn yellow balls like in the birth of the solar system and more like every time I get in 1st place it spawns something much bigger and I have problems with it but you're doing good keep up the great work! also add more galaxies like 10 and add multipliers like 2X 3X 4X and 5X the bots can't get it only players

love this app. the galaxy merger is my favorite. the original is better but the new one is still super cool!! I just like the freedom of the original merger better. although some of the simulators seem to not really work at all for me. also you guys should put in a play/pause button in the original merger and It just kind of sucks that the stars disappear after so long. still love it!!!

I'll make it a 5 stars if he adds more mini games about where you can make galaxies collide with each other including planets instead of making wants that costs money also I've been wanting to have a new mini game where you can spawn planets and the collisions are hyper realistic and it's not laggy I want a big update in the birth of the solar system making it 3D and I want the game owner to add another one that's just like the birth of the solar system but it's like today and universe sandbox

What’s new

Fixing the Sun’s intrinsic brightness in the 3D Milky Way map so you can see how bright the Sun would appear in the Proxima Centauri sky and around other nearby stars.
