A model for the distribution of dark matter is presented where the study of systematics considers the dependence of the dynamical mass on radius rather than on that of mass to luminosity ratio. It is suggested that neutrino condensates of 10 to the 16th solar masses were the first objects to be formed in the universe at a redshift of approximately 10 to the 4th, and that they subsequently expanded much slower than the rest of the universe. In the model, fluctuations in the density of baryonic matter grew effectively with the formation of the galaxies, and the dynamics of these galaxies are sensitive to the background gas. Assuming a 10 eV/c-squared neutrino rest mass, the details of the dynamical motions of the galaxies and the stars can be quantitatively understood. Results from the intensity and spatial correlations of the redshifted 21-cm line differ from previous results.
