Take a look at this picture - how many galaxies do you see? How many billions of stars does this represent? In what twisted universe can you possible imagine your "galactocentric" view.
that’s “Copernicus” and “possibly”
He has no idea of a "galazy" at all -- at best, he has the notion that stars were like the sun, only a lot further away (which couldn't be confirmed until telescopes got good enough to measure stellar parallax). If so, stars were presumably scattered randomly across space, continuing out to infinity in more or less the same pattern (which gave rise to the problem of "Olbers' Paradox" -- but I digress).
