Here's a question, why do you believe the universe must have a center?
Why does that seem any more theoretically possible than a universe
without a center?
A 3D axis doesn't do the universe justice. Just because a galaxy is
traveling 90 degrees on an x-axis, doesn't mean that it got there
through a straight line, or an arc for that matter. How many other
galaxies did it collide with before it came into view? Could you
actually backtrack all of the collisions and determine the center? Can
you determine the center of a volume of gas, by tracking the collisions
of it's molecules? Does the sky have a center? Only if centers are
allowed to be outside of the volume they are determined by. Is this
possibly the case with our universe?

I don't get it. Why do you say the universe doesn't have a center? I
mean,
if you could determine the positions of all galaxies then you could find
the center. (Not sure it's techically possible but it apepar
theoretically
possible.) Also on the same subject, can you determine the direction
galaxies are moving to in a 3D axis? If you know the direction a galaxy
going, you can determine where it came from. Right? I imagine relativity
should play a role here too, but I just don't know what it is, so I
suspect
there are several flaws in this paragraph.
