“To come up with the proper answer, one would have to determine the actual shape of the universe, currently that is quite impossible to determine given our earthly understanding of physics.”
I agree, It could be asymmetric. It could be asymmetric to a huge degree. They are using only the “observable” distances. We could be on the very edge of the actual universe. Like our solar system we could be in just one “Arm” of a spinning universe like a galaxy. And there may be millions of these galaxy type universes.
But these possible concepts are taboo to even consider or factor in because we can’t see it with our own eyes yet. And they won’t be until we can.
I'm gonna cheat. I'm gonna wait until I die and ask God.
