It is investigated whether observed large-scale streaming of galaxies represents velocities of dark matter under explosion scenarios. It seeems that, although individual galaxies will not represent motions of dark matter, cluster of galaxies follows the velocity field of dark matter. The origin and upper limits of such field are considered.
