Deep surveys indicate a bubbly structure on cosmological large scales which should be the result of evolution of primordial density perturbations. Several models have been proposed to explain the origin and dynamics of such features but, till now, no exhaustive and fully consistent theory has been found. We discuss a model where cosmological black holes, deriving from primordial perturbations, are the seeds for large-scale-structure voids. We give details of the dynamics and accretion of the system voids-cosmological black holes from the epoch till now, finding that a void of Mpc diameter and under-density of -0.9 fits the observations without conflicting with the homogeneity and isotropy of the cosmic microwave background radiation.
Key words: cosmology: large scale structure of Universe / cosmology: dark matter / black hole physics
