>who is thus momentarily at rest relative to the object being measured
How can you look at two objects and determine which is moving and which is standing still if there's no third object with which to compare them? That's the point of the OP. Retards ITT firing off the hip about "math" are just dodging the simple question.
Intuitively the answer is probably that the premise of the question inherently assumes an outside observer who occupies a single position and therefore constitutes a third object; if object one can observe ONLY object two, with no background, there can be no "movement" relative to object two, as object two cannot move closer to or farther from object one–"closer to" and "farther from" entail measurement of distance which must be performed relative to a background. In a hypothetical universe of two objects, object 2 is the universe of object 1. That is to say, from an "outside" perspective, there can be no movement relative to the universe; movement can occur only within the frame of the universe, by comparison to objects within it. Movement is, from an absolute perspective, an illusion.
Really this whole thread is about epistemic relativity.
