One very important consideration is what a given amount of "distance" would ____mean in an "expanding" universe, or indeed what it means for the universe to "expand". If your means of measuring distance are affected by the expansion, it is possible (probable?) that such a phenomenon would be undetectable and therefore without objective significance.
