This monograph places temporal asymmetry within Informational Monism as a structured family of related operations rather than a single master fact. At the local level, measurement is an irreversible commitment: a record anchored by dissipation Σdiss≥kBln2⋅Nrec\Sigma_{\mathrm{diss}}\ge k_B\ln2\cdot N_{\mathrm{rec}}Σdiss≥kBln2⋅Nrec is undone only with probability at most 2−Nrec2^{-N_{\mathrm{rec}}}2−Nrec.

This treatise develops Informational Monism as a unified ontological architecture for emergent spacetime, quantum records, and bounded agency. It rejects the premise of an ontologically primary spatiotemporal container populated by localized particles, and treats physical reality instead as a coarse-grained, error-corrected rendering of a deeper informational state. Reality is organized across three tiers: an unmanifest Meta-Background; a low-dimensional Code Circuit carrying a global unitary description; and a rendered bulk in which embodied observers encounter classical spacetime, matter, and records. Within this architecture, the treatise offers interpretive accounts of three central problems in foundational physics. Bell correlations are read through joint commitment at the boundary rather than through bulk signalling. Quantum measurement is treated as the actualization of a single irreversible record under a question-and-commitment discipline that preserves Born neutrality. Black-hole information is handled through complexity-resolved conservation: fine-grained unitarity may be preserved while remaining inaccessible to resource-bounded decoders. A Minimal Core of six postulates supports these proposals without modifying the predictive apparatus of quantum mechanics. Broader extensions — including the Horizon Model of the Dynamic Absolute, the Principle of Super-Balance, and the conservation of meaning — are developed separately and marked as dependent on further postulates. The work distinguishes direction from status in the arrow of time, states labelled conjectures and conditions of revision, and presents a research programme with near-, mid-, and far-term horizons. The result is not a claim of final theory, but a systematic non-dualistic framework in which geometry, record formation, accessibility, and agency can be discussed within one architecture.

The arrow of time is one of the most profound and persistent mysteries in physics. While the microscopic dynamical laws are (almost) time-symmetric, the macroscopic world exhibits a clear temporal direction. This paper introduces a records-based diagnostic criterion for evaluating explanations of temporal asymmetry: any successful account must explain why stable, redundant records of a system's state are generically produced toward the future, but not the past. We show how the established frameworks of decoherence and quantum Darwinism provide the mechanism for record creation, but that the temporal asymmetry of this process is not derivable from dynamics alone. Instead, it depends crucially on a low-entropy boundary condition—the Past Hypothesis. We then critically evaluate leading alternative explanations—including inflationary cosmology, quantum cosmology, and fluctuation scenarios—demonstrating that they either fail to meet our diagnostic criterion or covertly presuppose the asymmetry they seek to explain. We argue that the records criterion does not replace the Past Hypothesis but constrains what any replacement would have to accomplish. By distinguishing record formation as a dynamical process from record availability as an epistemic structure, we clarify that the arrow of time is best understood not as a feature of dynamics, but as a structural consequence of boundary conditions that permit asymmetric epistemic access for embedded observers. The problem of time's arrow is thus most precisely formulated as: why did our universe begin in a state that permits the temporally asymmetric proliferation of records?
AbstractThe origin of the arrow of time—why entropy always increases, why we can only remember the past—is one of the deepest puzzles in physics. Boltzmann’s statistical explanation attributes entropy increase to a low-entropy “past hypothesis,” but it does not explain the origin of this initial condition itself. Landauer’s principle reveals a quantitative connection between information erasure and heat dissipation, yet it does not answer why information erasure is fundamentally irreversible. This paper proposes a unified solution within the two-phase information conservation framework: the arrow of time is the macroscopic statistical manifestation of the irreversibility of information settlement between the material phase (Ξ) and the information phase (Ω). Each information settlement event simultaneously produces four outcomes: formation of an information record, local collapse of the material phase state, update of observer coherence parameters, and consumption of dark energy accompanied by heat release. Once settlement is completed, it cannot be undone; the unidirectional flow of time is precisely the macroscopic bookkeeping of this settlement irreversibility. Starting from the principle of least action incorporating two-phase coupling, we provide a rigorous proof that the settlement process is not invariant under time reversal, and derive a quantitative relation between the entropy production rate and the macroscopic information activity rate. This framework unifies the thermodynamic arrow, the quantum measurement arrow, the decoherence arrow, and the cosmological arrow as manifestations of the same settlement process at different scales, offering a natural explanation for the past hypothesis and the entanglement past hypothesis. We present three testable predictions: a weak dependence of the CHSH violation parameter on the measurement time difference in Bell experiments, a scaling relation between decoherence rate and information-phase coupling strength at ultra-low temperatures, and the gravitational memory effect as a cumulative signature of settlement records on cosmological scales. This work unifies the arrow of time with quantum measurement, black hole information processing, dark energy cosmology, quantum entanglement, the Higgs mechanism, and the third law of thermodynamics under a single cross-scale information settlement paradigm.Keywords: arrow of time, second law of thermodynamics, Landauer’s principle, information settlement, irreversibility, entropy increase, time-reversal symmetry breaking, gravitational memory effect, past hypothesis
Why does time seem to have a direction when the microscopic laws do not? This paper gives a rigorous answer. We show that if you look at a system at a fixed resolution where its dynamics are reversible and satisfy a standard regularity condition (a log–Sobolev inequality), then there is no intrinsic arrow of time: entropy production is exactly balanced by an equal “ordering flux,” a state we call entropy–order balance (EOB). The arrow appears only when we observe the system through a lossy filter—such as averaging, ignoring variables, or tracing out an environment. Mathematically, this is a channel that merges many microscopic states into the same observed outcome and therefore forces a one-way loss of distinguishability. The main result is an Arrow Structure Theorem: an arrow of time exists at a given resolution if and only if the observation map is genuinely irreversible in a precise information-theoretic sense. We quantify its strength using a new, scale-dependent number—the arrow intensity As(O;t)∈[0,1]A_s(O;t) \in [0,1]As(O;t)∈[0,1]—which measures how much distinguishability is lost and behaves like a resource that can only increase under further coarse-graining. The same mechanism applies in both the classical and quantum cases and allows one to predict and measure how quickly an observed description forgets details, and to compare the strength of the arrow across platforms using a single information-theoretic yardstick. Conceptually, the work separates what the world does from what we access and provides a structural resolution of Loschmidt’s paradox: the arrow is not a property of the microscopic laws, but of the lossy channels through which we observe them.
We present a unified operational framework for the arrow of time grounded in irreversible information loss. While microscopic physical laws are time-reversal invariant, macroscopic irreversibility arises when systems overwrite metastable records. We show that recent reversible quantum-control experiments do not reverse time, but instead operate in regimes where no logically irreversible record is created. To formalize this, we introduce the **forgetting rate** (Ξcr), a coarse-grained rate defined on physically selected metastable record states (e.g., pointer states, memory registers, or macroscopic configurations). Unlike standard entropy production, which is expressed in terms of microscopic transition asymmetry, (Ξcr) captures the **rate of irreversible record overwriting**. In this formulation, entropy production obeys the lower boundS˙irr≥kBΞcr,consistent with Landauer's principle but expressed at the level of record dynamics. Within this framework, thermodynamic, quantum-measurement, psychological, and cosmological arrows emerge as substrate-dependent manifestations of Ξcr>0. Temporal asymmetry is therefore not a single global property, but a distributed feature of physical information-processing systems. The approach naturally explains the decoupling of arrows in composite systems and identifies experimentally accessible regimes where irreversibility can be locally suppressed. This work does not introduce a new microscopic law but provides a unifying, operational reformulation that connects information thermodynamics, decoherence theory, and memory dynamics through a single coarse-grained rate.
This paper develops an interpretive account of the physical life cycle of records within a consistency-history framework. Earlier papers in the series characterized a committed record as “decoherence- and thermodynamics-protected, append-only in practice.” The present paper refines and partially corrects that formulation. A physical record is not logically immutable or fundamentally append-only. It is revision-resistant in practice insofar as its information is encoded in sufficiently protected physical degrees of freedom, often—but not universally—through metastability and free-energy barriers. The central claim is structural and deliberately deflationary: there is no single thermodynamic price of a record. Record formation, passive retention, revision, logically irreversible reset, active error correction, and redundant proliferation are distinct processes with different, implementation-dependent demands. The paper therefore replaces a scalar cost with a physical record profile comprising resources, performance, and architecture: free-energy and dissipation budgets, control resources, operation and retention times, error rates, and an effective number of sufficiently independent carriers or access channels. Landauer’s principle directly constrains the logically irreversible reset component of this profile. Other record processes inherit a Landauer-type constraint only when their implementation contains a reset or another logically irreversible information-discarding step. The formation of a classical record is represented as the logically reversible, in-principle correlation of distinguishable pointer states with an initially prepared memory. This is not the cloning of an arbitrary unknown quantum state, and a complete reusable memory cycle must still account for preparation and reset. The paper further distinguishes logical commitment, physical durability, and public finality. Public finality requires an operationally significant redundancy of sufficiently independent, accessible, and durable carriers or access channels. This is an architectural requirement, not a universal additive heat cost per copy. Environmental amplification may generate redundant records without implying a universal Landauer-type price for each environmental fragment. The framework derives no result in thermodynamics or statistical mechanics. It does not derive the second law, the Landauer bound, any fluctuation theorem, the thermodynamic arrow of time, or the low-entropy boundary conditions of the universe, and it makes no independent empirical prediction. Its contribution is a disciplined decomposition of the physical processes through which records are formed, protected, revised, erased, maintained, and made publicly accessible.
