"This cancellation may seem less strange if one notes that a similar effect occurs in electromagnetism. If a charged particle is moving at a constant velocity, it exerts a force that points toward its present position, not its retarded position, even though electromagnetic interactions certainly move at the speed of light. Here, as in general relativity, subtleties in the nature of the interaction "conspire" to disguise the effect of propagation delay."Or perhaps there is no significant delay. Hmmm, rather than having nature "conspire", perhaps Newton was basically correct that Gravity (who knows, possibly even the electromagentic field effect, too) propagated at near instantaneous speeds, say, the Speed of Light squared.
