I read that the cold dark matter model best fits the cosmic background radiation spectrum. I am puzzled by why most of the mapping of the distribution of dark matter shows it to be in halos about galaxies, rather than evenly dispersed with ordinary matter. The question arises from this distribution is; What pressure keeps dark matter in galactic halos and essentially out of planetary systems (Where Keplarian orbits reside, rather than the flat rotation curves of spiral galaxies)?
