the lambda-CDM model assumes the existence of a distribution of dark matter which is unique to each galaxy and empirically derived. That's potentially a (countably) infinite-dimensional free variable vector for each galaxy, although typically models assume dark matter is usually symmetrically distributed (which can still be a countably infinite-dimensional free variable vector, as a function of rho and phi at least). In any case it's got enough free variables to account for two drastically different cases - 'normal' galaxies, and diffuse galaxies, which apparently have no dark matter. How do you parameterize that without at least one free variable per galaxy? > If there were a better one, it would already be accepted. I see you've never actually been a scientist.
