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.
