In this simple simulation, at every tim

In this simple simulation, at every timestep each particle (red spot) moves along an edge at random to an empty location (if there is one). A central region has more connectivity than the rest. After a while the density inside the central region is higher than outside, because once a particle gets inside then most of the links from there take it to a location that is also inside.

You can see that there are more red spots in the middle than elsewhere.

This demonstrates how gravity could be an entropic force  - caused not by gravity waves or anything but by statistics alone.

This toy model is described in the cited Markopoulou, et al. paper on 'quantum graphity'.
