Ok - I am badly lost. Are we saying we have a map of the known universe, and it has a South Pole? I think this would be a cool
map to share - start putting copies up on school
walls like the Peters Projection
In any case, here's another one: https://in-the-sky.org/ngc3d.php
North/South pole are on that map.
Since we can observe the universe for the same distance in every direction, I guess it makes sense that we'd give the resulting sphere a north and a south pole.
