A Speculative Cosmological Model - Black Holes, White-Hole Big Bangs, cosmic Reset and an Infinite Cosmological Family Tree

This paper presents a speculative cosmological thought model connecting several concepts that have been discussed independently in theoretical physics: black-hole interiors, baby universes, white holes, cosmological bounce models and eternal cosmological evolution. The central hypothesis is that a black hole formed within an existing universe could potentially give rise to a new spacetime region constituting a separate universe. The parent universe would not be destroyed by this process and would continue to exist. Instead of assuming that the structure of matter falling into the black hole is reproduced in the new universe, this model proposes a fundamental “cosmic reset”. Matter and energy would undergo an extreme transformation, resulting in new initial conditions rather than a direct continuation of the structures of the parent universe. From the perspective of the newly formed universe, the transition could appear as a white-hole-like event. In this model, the hypothetical white hole would not necessarily exist as a persistent astronomical object within the new universe. Rather, the white-hole event would correspond to the Big Bang itself. The model further proposes that this process could continue indefinitely. There would not necessarily be a first universe or a first Big Bang. Instead, universes could form an endlessly branching cosmological family tree in which existing universes continue to exist while their black holes potentially give rise to new universes. This work is explicitly presented as a speculative hypothesis rather than an established physical theory. Its purpose is to formulate the proposed connection between these concepts clearly, compare it with existing theoretical work, and identify questions that would require mathematical and physical investigation.
