Paul Anderson, thanks for the pdf. Your formula employs the
electromagnetic assumption that gravity moves at the speed of light.

You got this backwards. In GR, changes in gravity propagate at the local
symmetry speed, given by SPECIAL Relativity. It "just so happens" [#]
that electromagnetic waves travel at this same speed in vacuum. It is
merely an historical anomaly that it is called "the speed of light", due
to the round-about way Einstein first described relativity in 1905 --
the spacetime symmetry is MUCH more fundamental and important.

Your formula (1) has c^2 and it is clearly not 1^2, and is in m/s,
contrary to Lodder.

Nope. YOU have imposed specific units onto the formula/equation. The

Relativity still thinks gravity is electromagnetism even after the

Reading about usual retarded and non-classical advanced potentials,
or Wheeler-Feynman and about Feynman saying "hey there's an invariance
or symmetry if you will here that does indicate a sort of standing
tension where electromagnetic waves live", gets into that much like
gravity, this sort of infinite-advanced-standing-wave concept
that has been arrived at by forefront physicists, requires a
super-classical approach, first mathematically, because without
the mathematics of these kinds things, there's no language thus
no physics of these kinds things.
https://en.wikipedia.org/wiki/Wheeler%E2%80%93Feynman_absorber_theory
"The theory postulates no independent electromagnetic field."
"Wheeler and Feynman postulate the "universe" of all other
electrons as an absorber of radiation ...."
I.e., whatever points from zero to one, there's
its inverse, space inversion.
Then, the arrow of time is just fine,
only that there's some sort of total field theory,
about both gravity, and, the propagation of EM waves.
