Universe Sandbox 2 was designed by Giant Army in 2012 as a simulator to create and destroy planets on an unimaginable scale.
Rated 4 out of 5 by Meta-Critic, this game is virtually capable of handling all aspects of physics without the need of a supercomputer.
Universe Sandbox 2 lets you simulate climate, gravity and temperature of planets, adjusting them in varying combinations to see out how the planet changes its appearance.
Control the carbon dioxide level of a planet and even add water to the surface to heat up or to cool it down.
In Universe Sandbox 2, a player can even deform a planet’s surface by colliding it with asteroids and comets to create large craters as well as destroy it completely by collisions with moons or planets.
Increase a star’s age or mass to see an evolving supernova.
You can build a planet with hydrogen, rocks, iron and water or completely finish it by planetary collisions.
Basically, you can control the whole universe, making galaxies and milky-ways coincide, travelling at the speed of light years all along.
