Well, yeah, i mean, since the universe has expanded in any direction
from a small point and at about the same max. speed (am I right?) it
must have kind of boundaries and be kinda like a ball, and thus have a
center... well that's how I see it, althought I never read anywhere
about a located center of the universe, maybe it's because we obviously
can't know due to the slowlyness of light.

Which makes me wonder, all those deep field galaxies we observe, we can
observe them in any direction, I mean, there's not a lone area of the
sky where only there can be found those early galaxies, right? In case
we can observe some of those all around us, how is it possible?
