The Universe is still expanding, but just not as consistently as the "Hubble Constant" assumes. In other words, is it that nobody can account for the velocity exceptions, while there might still be a rule there? Is there any other way of determining distance at the intergalactic scale? For example, in cases where we see light from a star directly as well as a refraction by an object in the foreground, is there a detectable phase shift from which we could calculate the height of the deflection triangle, and then know all of the distances?
The exceptions don't disprove the rule.
