   We really do not know the relationship between ordinary matter and dark   
   matter for certain. A general rule for the relative prevalence of   
   ordinary and dark matter is most likely beyond our knowledge.   
      
   Clumping of matter occurred with gravitational waves in the early   
   universe that got stretched into long wavelengths. These gravitational   
   waves caused matter to oscillate and with ordinary matter there is   
   enough friction by the production of electromagnetic radiation to cause   
   them to clump. Dark matter has no friction so its gravitational   
   interaction is purely conservative. With ordinary matter losing energy   
   by radiation (friction) this probably provided enough gravitational   
   potential to bind dark matter as well. This friction driven set of   
   oscillations started by gravitational waves turned into acoustical   
   energy in the hot medium of the universe in its first seconds to hours   
   of existence. This anisotropy persisted with the expansion of the   
   universe and is found in galaxies, galaxy clusters with dark matter   
   halos. Comparisons between anisotropy of the CMB and subsequent galaxies   
   is an ongoing program.   
      
   A galaxy with little or dark matter tends to suggest there was little   
   dark matter around to gravitationally bind to the ordinary matter, and   
   so there was some initial anisotropy of dark matter. That leaves a big   
   question to ponder. It is very difficult to address this question   
   because we have no experimental evidence on what dark matter is. Eric   
   Verlinde thinks dark matter is a type of spacetime physics, and with   
   gravitational radiation around there might have been something odd. If   
   dark matter is due to supersymmetric partners of ordinary matter, then   
   the action of supergenerators to give local spacetime transformations   
   might have played some role with primordial gravitational   
   radiation. Maybe, and then again maybe not.
