宇宙沙盒/Universe Sandbox

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

Simulate Gravity

N-body simulation at almost any speed using Newtonian mechanics Real science real physics no supercomputer required

Collide Planets amp Stars

Epic mind blowing collisions of massive planetary bodies that leave behind molten craters

Create Your Own Systems

Start with a star then add a planet Spruce it up with moons rings comets or even a black hole

Model Planetary Climate

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

Supernova a Star

Watch a supernova unfold by colliding two stars cranking up their mass or making them explode at your whim

Explore Historical Events

Hitch a ride with spacecraft including Juno and New Horizons or view a total solar eclipse

And more

Build and terraform planets with12 materials including water oxygen amp carbon dioxide

Stellar flares amp volatile trails

Procedurally generated planets stars amp galaxies

Pulsars

Light-warping black holes

Epic space lasers

Shape oceans amp mountains on planet surfaces

Spin planets apart with centrifugal force
