Dead Universe Theory (DUT) Continuum Cosmology: Quantum-Gravitational Simulations de 14.3 Billion Years — Predicting 166.2 Billion Years Pre-Big Bang

The ΛCDM model, although historically successful within the 13.8 Gyr observational horizon, fails to account for JWST evidence of massive galaxies, black holes, and dust at extreme redshifts [22]. Its reliance on an initial singularity [7] further restricts applicability to extended temporal regimes. The Dead Universe Theory (DUT) offers a deterministic and non-singular alternative extending up to ~180 Gyr. Through the DUT Quantum Simulator [12], we demonstrate that the formation of massive nuclei (~10⁷–10⁸ M☉) arises naturally from quantum-gravitational dynamics. Simulations resolve compact galaxies at z ≈ 30 (≈30 Myr after the Big Bang) and extend coherently to pre-Big-Bang states at Δt = –0.5 Gyr. When expressed in the ΛCDM ruler, these pre-BB structures correspond to an apparent lookback of ~14.3 Gyr, beyond the 13.8 Gyr horizon of the standard model. The framework further projects a fossilized universe at ~76.8 Gyr and an ultimate thermodynamic end near 180 Gyr. Thus, ΛCDM retains validity only within its 13.8 Gyr domain, while DUT governs the extended regime where forthcoming observations will critically test its predictions.
