 According to Whitehead, the Maxwell-Lorentz theory of electrodynamics (unlike Einstein’s GTR) could be conceived as coherent with our basic intuitions—even in its four-dimensional format, namely, by elaborating Minkowski’s electromagnetic worldview. Hence, Whitehead developed his ATG in close analogy with the theory of electrodynamics. He replaced Einstein’s geometric explanation with an electrodynamics-like explanation. Whitehead explained the gravitational motion of a free mass-particle as due to a field action determined by retarded wave-potentials propagating in a uniform space-time from the source masses to the free mass-particle.
