Fling Planets and Change Physics

Gravity Simulator lets you control one of the most basic forces in the universe. Launch stars and planets, and watch as gravitational patterns unfold. Peaceful conic sections, dancing spirals, wonderful spirographs, and plenty of utter chaos will appear before your eyes.

But your powers don't stop there - you can also change the underlying physics of the simulation. Maybe, instead of a 1/r^2 force law for gravity, you'd like to see what happens if there were a 1/r^2.1 force law. Or a tan(r) force law. Or any strange force law you can come up with. You can even turn on General Relativity, and see what happens in a world where a massive object warps space. What weird and fascinating universes can you create by playing with the laws of physics?

If you like what you've created, it's easy to save it and share with friends. Show off a work of art, an interesting physics phenomenon you discovered, or, ideally, both at the same time.

  • Accurate physics engine (what you see is what you'd get)
  • Easy-to-share codes let you show off your creations
  • Test out arbitrary force laws
  • General Relativity (black holes with Schwarzschild metric)
  • Change colors, masses, lines, density, etc
  • Customizable planet images, with built-in mod support to add your own
  • Achieve inner peace

You can explore this simulation - either in the free online version[testtubegames.com]
or by downloading the full version[testtubegames.com].

I'm excited to bring the simulation to Steam to see what you all can create!
