Thanks. I’ve seen this explained here many times, and I can never hear enough about the middle graf, the money graf.
But, as someone holding on to analogies with the skin of my teeth, in my 3-D physically perceived world, two objects on an expanding balloon do have greater distances between them at t+n. Their addresses on the map stay the same and their distances are always proportionally the same relative to tn-1, but separate they do.
Fucking analogies.
ETA: “…their distances are always proportionally the same relative to tn-1” is a pretty loaded, and wrong, sentence, I think. Is it? Spacetime can change non-homogenously, right?
