If this exercise is to demonstrate a center or a preferred direction to the expansion of the universe it won’t work. The singularity of the Big Bang was a density singularity not a space-time singularity. Inflation has made the universe (on large scales) isotropic, homogeneous and nearly flat. For now, gravity defines the galactic structure you envision measuring and is most structured at a local level. You could come up with any number of line-crossing looking at galaxies within the local group. The Virgo Cluster (the one in which our Milky Way galaxy resides) is moving toward the Great Attractor within the Laniakea Supercluster. That’s a bunch of line-crossings, but this in no way defines a center for the universe. If this is not what you are asking, then I didn’t understand the question. Have fun exploring, Dave
Greetings,
I am not an astronomer, but have scientific background (chemistry) look at http://knowledge.electrochem.org/estir/editor.htm if you want to know more about me.
I have a question which may sound bizarre, I already apologize.
As far as I understand, the universe is expanding and the galaxies move away from each other.
Take two galaxies that move as close as possibly 180 degrees opposite directions, and draw a straight line between them. Find as many such pairs as you can, and see if the connecting lines cross at a fixed point, or at least close to each other. I think it would work better if the galaxies were about the same age.
If there is such a point that must have some significance, but what?
Regards: Zoltan Nagy.

If he lived anywhere but here, that scope would have sold quickly. Either coast, or the midwest. But we just don't have that many people around here who are seriously interested in observational astronomy. Much smaller market for used scopes.
