Iliyan, that’s a really really nice video but it still does not explain the motion, the excellent “why” of your earlier comment. Here’s an idea involving a background-dependent quantized space:

Consider the “empty” volume of our universe to come in tiny grains of space and moments of time. The grains consist mostly* of potential properties, that is, abstract, unmeasured space-time properties. (The grains emerge into s/t from the immaterial background (of abstraction, but, more on this sometime…). Within each quantized moment, there is, of course, no change (motion) so the grains maintain a fixed relationship to each other. Occasionally, a grain’s unmeasured properties become measured. When this happens, a grain can no longer maintain its potential nature and collapses down to a discrete particle of smaller size. Leaving an otherwise perfect vacuum around the particle, we find in the next moment that the collapse has caused the volumes (*discrete) of the neighboring grains to be pulled in from their fixed positions (* discrete) towards the newly-emerged particle, elongating them in the process towards the new particle. The region now looks something like a 3-D asterisk, or dingbat. The elongation of a grain’s volume leaves it with an additional property for the action; a measured idea of its motion in a particular direction. Later on, if such a grain is itself collapsed, the idea of its motion will become expressed in the evolution of the newly-emerged particle’s trajectory. I think it could be the idea of that motion that we call "gravity." Any object evolving in regions which have been conditioned in this manner will be affected by the inherent motion of the elongated grains.

Iliyan, Pravit, You can read more about this idea in appendix G of my book (2019). Lmk if I can email you a copy.
