Might dispersed matter have a higher mass than more condensed matter as an alternative hypothesis? Where the more distant and small a unit of matter is, the more curved the spacetime around it. Lonely particles longing to coalesce? These particles would reflect and scatter too little to be visible and hence be "dark matter". If this was the case, stronger attraction at either extreme of distance might be an effecient accelerator of formation of celestial bodies. This kind of wonky gravitation could also explain the accelerating expansion of the universe.
