Drop a few points of order onto the mesh below. Nothing pulls on anything else here — the grid just bends toward wherever the configuration is densest, and whatever drifts through follows the bend. Switch to force view to see the version with arrows instead, the one that implies something is reaching out and grabbing.
Each point of order lowers the local entropy of the field around it. The mesh simply sags toward whichever region has the least of it — the same way a taut sheet sags under a low spot, not because the sheet is being pulled, but because that is what an unconstrained sheet does once the low spot exists. Particles crossing the mesh follow the shortest path across whatever slope is already there.
Force view draws a vector from every particle to every mass, as if each one were reaching across the gap to grab the other. It is a useful shorthand for arithmetic — the numbers come out the same for two ordinary masses — but nothing in this picture is actually reaching. Turn the toggle back and the arrows disappear along with the implication that gravity is a thing doing the pulling, rather than a shape the field was always going to take.
