Spherical Multiverse: A Theoretical Framework for a Perpetual Cosmological Model

The nature of the universe and the mechanisms driving its evolution remain subjects of intense research and debate. This work presents a theoretical model of a spherical multiverse in which the collapse of one universe (Big Crunch) initiates the expansion of an adjacent universe (Big Bang) through energy transfer processes. This mechanism ensures continuity in cosmological evolution and prevents thermal stagnation. The proposed mathematical framework extends the Friedmann equations to incorporate energy transfer between connected spherical universes. Additionally, the model introduces the concept of positive and negative dimensions of time and defines a habitable zone at the equator of each sphere, where physical conditions remain stable for life over long periods. This framework aims to deepen our understanding of cosmic dynamics and open new avenues for research in cosmology and theoretical physics. Key aspects include the role of entropy reconfiguration in avoiding thermal stagnation and the potential observational signatures of inter-universal energy transfers in the cosmic microwave background.
