They don't?? The dynamic and highly mobile Fluid of space IS both cause
and mechanism. And it's not just "our idea" but that of a number of
people worldwide who have independantly come to see exactly the same
mechanism of gravity f'rinsance.
..and they predict speeds of gravity much less than that
predicted by
general relativity.

So what is the 'speed of gravity' under GR? It's c, right? Wrong. It's
instantaneous, just as Newton originally observed. GR does not predict,
mush less recognize, velocity of spaceflows. Yet the *acceleration rate*
of spaceflows is the determinant of the "force of gravity". GR
brilliantly but abstractly renders it as "curvature of space", and the
math attending it has proven wonderfully predictive.. within its limits.

"Within its limits" is the operative term. Relativiy
`describes` space mathematically as a universally-isotropic
'void-nothing' all the way back to the instant of the BB. As such, it
recognizes no density/volumetric gradients in the spatial medium, such
as exist in gravity wells (and show up in the Pioneer anomaly), and in
deep-cosmological frames (rendering such axioms as "ever-accelerating
expansion" of the universe). Because relativity does not recognize these
gradients, it is presntly 'flat'.
Bringing both SR and GR out of their present 'flat' status
requires recognizing the very real spatial medium and the
density/pressure/volumetric gradients at play everywhere in it. This is
the natural expansion and 'Upgrade' of relativity.. just as relativity
itself was an 'upgrade' of Newton.

As for the speeds, i believe we've
already covered those, but i'll reiterate...
the gravitational effect still happens at
the speed of light, and the gravitic
charge is still instantaneous.

Well again Paine, what you're terming "gravitational effect which
happens at the speed of light" can only be 'gravitational waves', not
gravity itself.
