" In practice, though, the simulation would need very, very high precision and to run for a very, very long time, and until we are running Universe Sandbox on a supercomputer, ring gaps won’t develop spontaneously."
Aw, for a moment I thought you made the rings develop the resonance on their own. Awesome though.

Orbital resonances should form a whole lot easier with planetary accretion sims though, I think.
