We need a stickythread that makes this point. Prominently so it catches newcomers' attention. Otherwise questions about it keep coming up. If anyone wants to try saying this in an especially clear way, please go ahead. Everybody I can think of has made this point----the mods, the professional astronomers that post here etc. We should have a Cosmology FAQ. the kindergarten basics. Any one of half a dozen people here could either write the whole thing or contribute paragraphs. Russ, Wallace, SpaceTiger, Kurdt, Janus... Now I can think of half-a-dozen more! How would YOU explain to a noob that it is standard in cosmology for distances between stationary points to expand FTL?
