Talk:Weak-field approximation

Far-field versus Weak-field

Actually, far-field theory treats gravitation far from massive objects. In such regions, the field is indeed weak, but weak-field theory is more general. In particular, it also treats the production of gravitational radiation by say a binary star system.

The rest of the current article actually discusses the Newtonian limit, another special case of weak-field theory, where we also assume that test particles are moving slowly with respect to the speed of light.

I propose to rewrite the article to clarify these points.
