First of all, John, you have probably surmised by now that I agree
with you that gravitation is a PUSH FORCE and neither a pull force nor
a wimpy effect.
I also agree that the galaxy rotation curve cannot be explained by
Keplerian laws. So scientists have invoked the mysterious "dark
matter" to explain it. Quantum mechanics yields the answer with the
postulated "spacetime foam". This foam may actually *comprise*
spacetime rather than just "being in it". Either way, the mass of
spacetime foam would not only explain dark matter over gigantic areas
of spacetime, such as found within the confines of a galaxy, the foam
would also fit within a PUSH-FORCE theory of gravitation without the
problems of the old, Le Sage-type models. Spacetime foam might "flow"
into matter, with mass acting as a flow-sink, and cause gravity.

In a "spacetime-foam model" of gravitation, there would be only the
absorption by matter of the spacetime foam. Plus, in this type of
model, one would be able to get rid of the "push vs. pull" mental
image of gravitation. Since the formulas work either way, push or
pull matters very little, and the relativistic "effect" of matter on
spacetime would also be a keeper, as long as it is recognized that the
spacetime foam does actually "forcefully" flow into matter to keep our
feet on the ground.

Well, there's really no way of knowing what is actually forcing
spacetime foam into a highly pressurized, extremely energy-dense
system that actually sustains the forces of each and every atom of
matter it flows into and through. Any description of such a driving
force would be an even less credible type of speculation, simply
because the driving force would have to be so great that it could not
be anything astronomers have observed thus far.
The important thing is that matter does not actually "cause"
gravitation, because matter, even the matter of which you speak above
(non-local) is just not much of a power source. What is needed is a
powerful ENERGY source and some idea how to convert energy into
matter. THAT is the type of driving force that would actually CAUSE
the spacetime foam to flow into matter.
It's not really "incorrect" to say that matter causes gravity. Just
as with spacetime foam, if that concept is correct, we can say that
spacetime foam causes gravity. Each time we step to a new level, the
question will ALWAYS remain, i.e., "What causes matter to 'attract'
things?" Ans. "spacetime foam". "What causes spacetime foam to flow
into matter?" Ans. "use your imagination and speculate". What causes
*whatever* it is that you imagine? (and so on, and so on).
Our present level of technology, while rising more quickly, say, than
a decade ago, is still insufficient to be able to confirm spacetime
foam, let alone what the magnificent force would be that drives
spacetime foam into all matter.
Now, "dark ENERGY"! That's another story!
