Individual Galaxies are bound by gravity to eachother and to the centers of galaxy clusters. You have to get out to the superclusters of galaxies to see expansion that isn't clouded by mutual gravity attraction. The isotropic nature of expansion is demonstrated in the cosmic background radiation. Long ago all the hydrogen gas in the universe was ionized into a plasma. As expansion progressed this plasma cooled until protons could capture and keep electrons and atomic hydrogen became the norm. This phase change came with a large pulse of photons as the atoms settled into the ground state. This pulse of light is the CMB. By carefully studying this we can conclude that expansion has no preferred direction. Also, and it's hard to understand, the expansion is caused by new space being born within the existing space, not by objects merely moving apart within a fixed space. Fixed space is a local illusion not a universal fact.

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?

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.
