"Expansion could not explain it. The expansion
of matter (not space), would have to result in unit intervals
that constantly change (increase in length, meter sticks
made of matter expand, time slows, the temporal units
lengthen).

I dom't know what you want, vector values in
polar or rectangular coordinates?

No, and Newton can't explain how "gravitational
forces" cause the moon to fall one-eighth of an inch
every second.

I don't see the answer as the big deal, science
understanding results from discussions of speculative
proposals.

Because I want to. To my satisfction, I have,
and I am comfortable with the explanation.


>Why does gravity need a "mechanism"?

Perhaps If I would not have stumbled on the
popular books by Einstein in the early 1950's (with
some pages removed by the FBI 10 years earlier),
and the Dover paperback by Einstein, Minkowski,
Lorentz and Weyl, I might have stopped thinking
about the nonsensical expansion model.
But my interest really peaked when my
astronomy professor who worked in Africa in the
big worldwide gravimeter project told me that
"the density of the Earth increases faster than
the square of the radius at that level.
It became a challenge to explain how
the acceleration of gravity could be greater
a few hundred miles below the surface than
it is at the surface.

Yes, but it was simply Euclidean space,
which has no explanation.

The Divergent Matter model is clearly
possible with contact interactions, ONLY.
All other models seem to need hypothetical
particles, computer controlled ether medium, or
radiation "billiard balls" coming from all directions.

I know all gas molecules repulse each other,
so expansion would not require anything new or
unknown.

Newton, in creating the most useful and
least complicated mechanics for energy, motion
and gravitation, specified that gravitational mass
be identical to inertial mass, that is what the
formula actually says.
At least Einstein saw that this was just
too much of a coincidence, and devised a
principle that absolutely requires processes
that identify them not as equal or even identical,
but two words for the same attribute of matter.

Would you have asked Einstein why he
felt compelled to think about gravity?
