I'm going to peruse this, it discusses the stuff you spoke about:

My math is quite rusty and so it'll be a struggle.
This is interesting, so what is there in the Newtonian inverse square law that leads to the infinite propagation speed? Why does Maxwell's field formulation have a concrete propagation speed but Newton's does not?
OK.
So if we consider Newtonian gravitation for a second, would it be true (leaving GR aside for now) that that is a classical field theory?
What was making it hard for them to see GR as a field theory back then? what was it that changed that?
Thanks!
I'm reading on Wikipedia about quantum field theory and read this:
"Quantum field theory naturally began with the study of electromagnetic interactions, as the electromagnetic field was the only known classical field as of the 1920s".
Why wasn't Newtonian gravitation regarded as a classical...
