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.
