When it does, its gravity will cause the quasar's position in the sky to shift by a distance that depends on the speed of gravity

Well, I'm no physicist, but this don't pass the smell test.
Speed (unit-of-distance over time) is not Force (ergs) is not Velocity (speed+direction).
Does gravity respect particle theory?
