Description

This gravity simulation is a sandbox on a grand scale. Put planets, stars, and asteroids in place, give them an initial push, and see where they go. Observe the conic sections that emerge from the simple rules of gravitational attraction. Why stop there? Go ahead and simulate what we might observe if gravity deviates from a 1/r^2 law. Change the law just a little, and try to recreate the strange and famous behavior of Mercury. Throughout it all there will be beautiful and captivating pictures. So go make some worlds, and make some art.

History

This was one of the first projects Andy created - starting as a flash game way back in 2011. He was just starting out as a developer, and figured gravity would be an easy science concept to simulate. He was wrong. What started as a basic simulation grew and grew - with optimizations and numerical physics algorithms this naive theoretical physicist hadn't realized existed. Add to that the constant scope creep of new features - and this project just kept going, with ever more updates. In 2014, the sim was converted from flash into Unity, and a beta of the downloadable version was released. Finally, in 2016, Gravity Simulator (non beta!) was released -- and the gods of scope creep only know what's in store for this project next.

Features

About TestTubeGames

Boilerplate
TestTubeGames is an independent games studio based in Cambridge, Massachusetts. Andy Hall founded the studio in 2011 with the mission of bringing theoretical physics to games. He works from the ground up, trying to find the fun, interesting puzzles in a subject. Then he adds in cute animals, slaps in several dozen puns, and goes into a cave for several months of devoted meditation to come up with the titles.
