Are you sure that this has to do with Dark Energy? Dark Energy is an unknown form of energy that must appear in Einstein's equation in order to make the universe accelerate at its current rate. Are you saying that: 1. Dark Energy only makes the space near it expand and has little to no effect on faraway regions? 2. Dark Energy is not present in places which has high matter density. Therefore, space in places with high matter density do not expand at the same rate as other regions (which contain Dark energy)?
