The Dead Universe Theory (DUT) Simulator 1.0: Exploring the Final Cosmos Through Non-Singular Quantum Gravitational Computation

The Dead Universe Theory (DUT) introduces a novel cosmological framework in which the universe evolves toward a final state of thermodynamic and quantum equilibrium, challenging the conventional Big Bang paradigm. This study presents a computational analysis based on the DUT Simulator 1.0, which models gravitational collapse, entropy gradients, and vacuum structure without singularities. The simulator applies regularized gravitational potentials and quantum thermodynamic parameters to describe the internal dynamics of a closed cosmic system. Simulations accurately reproduce the observed properties of high-redshift massive galaxies detected by the James Webb Space Telescope, including CEERS-1019 (z = 8.67, M⋆ ≈ 1.1 × 10<sup>10</sup> M☉) and GLASS-z13 (z = 13.1, M⋆ ≈ 1.5 × 10<sup>10</sup> M☉), with an average deviation below 5% in stellar mass estimation. Additionally, the model explains the emergence of structural stability in extreme gravitational regimes, offering falsifiable predictions about the long-term decay of entropy and the cessation of cosmic expansion. This article also proposes experimental pathways for DUT validation through observational astrophysics and controlled laboratory analogues. By integrating quantum information dynamics with gravitational thermodynamics, DUT offers a consistent alternative to ΛCDM, particularly in addressing the cosmological constant problem and the entropy flow in late-universe scenarios.
