The simplest interpretation of the CMBR dipole anisotropy is that it arises due to our motion with respect to the cosmic rest frame. However, the existence of a superhorizon-sized isocurvature perturbation can give rise to a dipole anisotropy intrinsic to the CMBR. In this case the cosmic rest frame and the CMBR rest framedo not coincide, and when viewed from the CMBR rest frame the universe appears “tilted”: matter streams uniformly from one side of the universe to the other. The intrinsic dipole model provides an explanation for the puzzling observation that most of the matter within a l00ℏ-1 Mpc cube centered on our galaxy has a large velocity (of order 600 km s-1) with respect to the CMBR rest frame.
