But this is not done. From this would follow, that we have entirely wrong views about the universe, because far away also means long ago. Now it doesn't make much sense to assume, that a foreground objects can interact with something in the past, we explore entirely impossible relations, if we try to figure out, how such relations function. Now this is actually done by cosmologists, if they explore e.g. black holes or gravity between galaxies. But because it is impossible to remove that distortion caused by the delay, cosmologists do, what they know it is wrong, because otherwise they had nothing to do. TH
