This paper presents a complete, self-contained mathematical and physical resolution of the Arrow of Time problem. It shows how irreversible thermodynamics, entropy growth, and the observed direction of time emerge from fundamentally time-symmetric quantum and gravitational laws using a spectral thermodynamic framework. The work unifies the quantum, thermodynamic, and cosmological arrows of time through a canonical bridge construction that preserves unitarity and OS-positivity while producing measurable entropy-monotone functionals. It reproduces the second law, Page-curve behavior, and Hawking/Unruh temperatures directly from first principles without ad-hoc statistical assumptions. The model provides falsifiable predictions for entropy flow and spectral observables and establishes universality across black-hole, cosmological, and laboratory thermodynamic systems. It represents the first fully quantitative, falsifiable, and universal derivation of time’s arrow consistent with quantum gravity and information conservation.
