Gravity Simulator

Author Comments

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.

For even more features, take a look at the downloadable version here: http://testtubegames.com/gravity_full.html

I Don't understand this too but it's Great

there is a bug in the game that happens right away that you can no longer zoom in, generate planets or move around the map I wanted you to fix this problem because I have to restart my game every time it happens

I like to make figure eight rings in orbiting planets with dust but its very hard

Very simple art style (that's great imo), and super relaxing music. I love how the physics feel soo real for simple game like this one. Great job!

An absolutely fun, peaceful simulator. It's a lot like a virtual zen garden, which makes it that much better. It's a great time waster, but I love that you can code your own physics if you want to get serious. Overall, great job.
