We propose a conceptual framework exploring the possible emergence of daughter universes insideblack holes.The model is based on the hypothesis that space-time possesses a finite maximum density, preventing the formation of physical singularities during gravitational collapse.When this critical density is reached, the internal geometry of the black hole may undergo adynamical transition leading to a cosmological bounce and the emergence of an expanding spacetime region.Possible connections with several approaches to quantum gravity are briefly discussed, as well asthe cosmological implications of such a mechanism.
