He Dead Universe Theory (DUT): The Asymmetric Thermodynamic Retraction of the Universe and the Foundations of Cosmic Infertility

His article presents an extension of the Dead Universe Theory (DUT), intro-ducing two original conceptual frameworks: asymmetric thermodynamic retraction and the foundations of cosmic infertility. The central hypothesis is based on the growing imbalance between the declining rate of galaxy formation and the increasing prevalence of structurally exhausted galaxies. It is proposed that the universe is undergoing a non-explosive thermodynamic regression, governed by entropy rather than by expansion or collapse. In this scenario, cosmic structures progressively lose their reproductive capacity, resulting in a slow but irreversible reduction in structural complexity. The theoretical model defines the net galactic function as dN/dt = N_f - N_d , where the extinction rate surpasses the formation rate. Simultaneously, matter availability follows dρ_m/dt = -αρ_m (α > 0), indicating an entropic depletion of structural resources. Despite the absence of a final gravitational collapse, entropy continues to grow, as expressed by dS/dt > 0, leading the universe toward a state of irreversible thermodynamic dormancy. This hypothesis can be empirically tested using deep-field data from the James Webb Space Telescope by analyzing the ratio of extinct to active galaxies, identifying regions of gravitational mass without star formation, and mapping voids that exhibit structural infertility. As a novel contribution, a Structural Natality Index (SNI) is proposed to quantify the universe’s remaining capacity for structural reproduction. The DUT framework, when combined with a time-variable Friedmann equation, suggests that the final stage of the universe may not be collapse or infinite dispersion, but rather functional exhaustion marked by a loss of cosmogenic fertility.
