  Recently, the gravitational polarization of the quantum vacuum was proposed
as alternative to the dark matter paradigm. In the present paper we consider
four benchmark measurements: the universality of the central surface density of
galaxy dark matter haloes, the cored dark matter haloes in dwarf spheroidal
galaxies, the non-existence of dark disks in spiral galaxies and distribution
of dark matter after collision of clusters of galaxies (the Bullet cluster is a
famous example). Only some of these phenomena (but not all of them) can (in
principle) be explained by the dark matter and the theories of modified
gravity. However, we argue that the framework of the gravitational polarization
of the quantum vacuum allows the understanding of the totality of these
phenomena.
