Woot?? My friend, you didn't passed the subject, seemingly. The visual is
the best you can do Physics, then here, in Relativity, specifically the GR
one. YOU CAN'T DO BETTER THAN the VISUAL, which IS geodesic, a PROJECTION.
Nobody can. You have much to learn, young man.

Wow, I suspect an accl to force confusion already!!

Not sure it has to do with "separations". Density yes, but you are
ignoring the CRYSTAL STRUCTURE, which can be rigid(er), whereas your
"separation vector" becomes totally obsolete, in fact wrong choice.

These symbols explain no _action at distance_, much less Forces, then it
doesn't impress anybody. Better luck next time.
