Either gravitational dynamic is very surprising to me, or this simulator uses an excessively simplified model. Once an object orbiting around an other, it seems almost completely immune from perturbation by other masses.

I'm sure it's greatly simplified: every thing I flinged went into a nice orbit! How did they do that? I recently was tinkering with a gravity simulation thing, and because I couldn't figure out how to make things orbit nicely I just gave up and made that the main game mechanic for a Ludum Dare competition entry https://mrspeaker.github.io/ld38/.

Dunno, I created 3 objects and they all gravitated towards the center of the triangle.

Sounds like a 2-body simulation like KSP.

The black hole is a nice way to cover the limits of the Sim

It seems to me that masses can only be created by steadily increasing the diameter of a roughly spherical body, presumably of constant and uniform density. Is there any way to vary the uniform densities of bodies? So I could create one small dense body with the same mass as a big diffuse one?

I wonder sometimes if our universe was created this way - define some basic rules, start an experiment, invite other gods over to build whatever they can imagine, watch the results and share on some cosmic Facebook.

Does nothing? Shows an "Update chrome" button but my Chrome is the latest.

Same here.

I used to spend hours playing with a different one of these trying to create binary systems with orbiting planets. This one looks cool visually but I don't like how when objects collide they just disappear.

Buggy and unconvincing.

Excellent, what a great demonstration and execution, thanks for sharing :)
