A Conceptual Framework: Black Holes as Gateways into a Shared Timeless Vacuum Reservoir and the Extended Big Bang

This preprint explores a conceptual framework in which black holes do not end in singularities but instead transition into a shared, timeless vacuum reservoir. I propose that this reservoir represents the same pre-geometric state that preceded the Big Bang, and that all black holes across all universes may feed into this single substrate. In this view, our universe may have originated from the interior of a black hole in a parent universe. The Big Bang is interpreted not as a single explosive moment, but as an extended transition during which the new universe is “fed” by the collapse of the parent black hole through the timeless vacuum. This provides a possible explanation for early-universe expansion, uniformity, and the continued acceleration associated with dark energy. The goal of this work is exploratory and conceptual rather than mathematical. It aims to connect ideas from black-hole physics, quantum vacuum states, bounce cosmology, and the breakdown of classical time. The hypothesis is offered for discussion, critique, and further development.
