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
