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

Abstract This article presents an extension of the Dead Universe Theory (DUT), introducing 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 = Ṅ_f − Ṅ_d, where the extinction rate surpasses the formation rate. Simultaneously, matter availability follows dρ_m/dt = −α ρ_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. Unlike traditional models where light and stellar activity define cosmic vitality, this theory presents a universe born from the ashes of a vast and dark predecessor, where light appears not as a constant, but as a rare anomaly. It challenges prevailing paradigms by proposing that the observable universe, with its stars and galaxies, resides in the core of a colossal black hole — the heart of the dead universe — where the conventional laws of physics intertwine with the arcane rules of a universe that no longer exists but still profoundly influences the cosmic landscape we observe. This entire predictive framework — encompassing the entropic black hole embedding, the negative curvature derivation, the Ωₖ = −0.07 ± 0.02 value, and the embedded numerical figures — was originally established and published in prior foundational work. The Dead Universe Theory (DUT) predicts that the observable universe is a confined entropic anomaly embedded within the gravitational well of a primordial structural black hole. This model naturally leads to a thermodynamic retraction scenario, explains the asymmetric decline of galactic formation, forecasts the eventual cosmic infertility, and proposes computational simulations for entropy growth, energy depletion, and matter segregation across multiple gravitational layers.
