The Hubble flow is the general outward movement of galaxies and clusters of galaxies resulting from the expansion of the universe. It occurs radially away from the observer and obeys the Hubble law. Galaxies can overcome this expansion on scales smaller than that of clusters of galaxies. The clusters, however, are being forever driven apart by the Hubble flow.
