The Erasure of History: Record Classes in a Closed Timeless Universe

Mustafa Boudjerada

This work studies the fate of historical records in a closed timeless quantum universe. Combining the theory of quantum records with the Page–Wootters framework of relational time, we investigate whether history possesses a fundamentally protected record class in a constrained universe. Using an exactly solvable Feynman–Kitaev constraint Hamiltonian, whose zero-energy states are history states, we verify three mechanisms: 1. No protected history class: every individual record can be erased by a later allowed deformation of the dynamics. Unlike positivity-protected records, a closed constrained universe contains no analogous unscreenable charge protecting history. 2. The erasure curve of history: the distinguishability of past records follows an exact interpolation as the erasure interaction is increased, while the global quantum state remains perfectly unitary. The past becomes unreadable, not physically undone. 3. Redundancy protects history: when events are copied into multiple independent records, partial erasure leaves the remaining copies intact, while only complete destruction of all redundant records removes practical access to the past. The results provide a minimal exact model showing that the apparent permanence of history is not necessarily a fundamental conservation law, but can emerge from information redundancy and proliferation. The model is not a cosmological simulation; it isolates the information-theoretic structure of history records in a closed constrained quantum system. Reproducibility scripts and audit variants are included.

Bohmian histories and decoherent histories

James B. Hartle

The predictions of the Bohmian and the decoherent (or consistent) histories formulations of the quantum mechanics of a closed system are compared for histories---sequences of alternatives at a series of times. For certain kinds of histories, Bohmian mechanics and decoherent histories may both be formulated in the same mathematical framework within which they can be compared. In that framework, Bohmian mechanics and decoherent histories represent a given history by different operators. Their predictions for the probabilities of histories of a closed system therefore generally differ. However, in an idealized model of measurement, the predictions of Bohmian mechanics and decoherent histories coincide for the probabilities of records of measurement outcomes. The formulations are thus difficult to distinguish experimentally. They may differ in their accounts of the past history of the Universe in quantum cosmology.

Macroscopic Determinacy and Microscopic Event Openness

Wonsik Choi

This paper investigates the physical boundary between macroscopic determinacy and microscopic quantum event openness within the WRRA SOURCE–RENDERER–PHENOTYPE framework. It distinguishes Planck’s constant ħ as the universal quantum of action, the mode-dependent energy quantum ħω, and qΦ as the minimum operational phenotype event that becomes distinguishable and persistent within a specific detection channel. Using quantum instruments, Born probabilities, decoherence, pointer states, environmental record redundancy, quantum Darwinism, process tensors, and non-Markovian dynamics, the study explains how probabilistic microscopic possibilities become effectively fixed macroscopic histories. It also separates standard quantum-mechanical predictions from WRRA-specific ontological assumptions, defines local and objective phenotype thresholds qΦ,loc and qΦ,obj, and proposes a falsifiable direction-history experiment designed to detect residual effects beyond standard process-memory models. The paper concludes that macroscopic determinacy is not universal future determinism but effective historical fixation produced by stable, redundant environmental records.
