Hello, I've read the article at http://pages.erau.edu/~reynodb2/LineweaverDavis_BigBang_SciAm_March05p36.pdf that was recommended several times on this forum. At the question "Can we see galaxies receding faster than light?" they answer: "Sure we can, because the expansion rate changes over time. The photon initially is unable to approach us. But the Hubble distance is not constant; it is increasing and can grow to encompass the photon. Once that happens, the photon approaches us and eventually reaches us" I know that we can see these galaxies. I just don't understand their explanation. Could someone help me understand? Thanks, Virgil.
