* Idea: Originally, a prerelativistic theory of gravity proposed in 1893 by Oliver Heaviside, based on an analogy between Maxwell's theory of electromagnetism and gravity; It is a flat-space, linear theory with no self-interaction, but the retardation of the field due to the speed of light is taken into account; In the current view, it is a special-relativistic theory that arises in the slow-motion, weak field approximation of general relativity.
* Field equations: The analogs of Maxwell's equations are (H = constant introduced by Heaviside, such that (G/H)1/2 = c)

∇ · g = –4πG ρ ,    ∇ × g = –∂h/∂t ,    ∇ · h = 0 ,    ∇ × h = –4πH ρ v + (H/G) ∂g/∂t .

* Idea: Gravitomagnetic fields arise from moving matter, like magnetic fields from moving charges, or from distributions of gravitomagnetic monopoles, if they exist (this requires torsion); They do not arise in scalar gravity.
* Clock effect: A deviation from Kepler's third law for a particle in orbit around a (slowly) spinning body, such as a typical planet or star, in the weak-field and slow-motion approximation of general relativity; i.e., a change in the period of revolution of clocks; > s.a. Wikipedia page.
* Other examples: Precession of planetary orbits (not a good test); Precession of gyroscopes; These effects arise in a post-Newtonian, special relativistic treatment of gravitation.
