> unintuitive I don't think it's just you. Maybe I can help; unfortunately developing intuition without going through the mathematics even at an introductory level [as in [1]] is a hard road. The tl;dr is that the objects are certainly moving apart; the question is whether or not the distance between them is increasing, and that depends on the coordinates in which one measures distance. In the cosmological case (and there are others in other areas of physics) the distant astrophysical objects aren't moving spatially in one particular set of coordinates, and that set is deliberately…
