To show this, we have to find the dialectical contradictions. Attraction and repulsion is an application of the 3. It restricts the possibilities of forces according to the 2. Axiom of Forces - it isn't a source of motion and evolution. Cosmological evolution is grounded in the expansion-impulse.
Expansion is the last ground of cosmical structur-building.
It doesn't destroy our materialistic point of view. This search shows, that I assume the possibility for science to reflect dialectical contradictios too. In my opinion essence includes contradictions. If science is able to do that, I didn't know.
