Sorry, no etymologies found.
So all we have to do now is to actually discover DM in the laboratory, measure its properties and find that they are concordant with astrophysical (Galaxy rotation profiles, cluster dynamics, Bullet Cluster) and cosmological (Large scale structuring, ‘cuspiness’, CMB fluctuations) constraints and then and only then we will really know what we are talking about.
