A Unified Informational Theory of Update Latency, Erasure Thermodynamics, and Physical Reality

We develop a long-form speculative but mathematically structured framework in which physical reality is modeled as a finite-capacity state-update process rather than as a passive archive of coexisting states. The central hypothesis is that a broad class of physical phenomena—local time dilation, inertia, acceleration-induced thermality, gravitational attraction, black-hole horizon behavior, and cosmological acceleration—can be interpreted as different manifestations of a single informational architecture governed by bounded local load, update latency, and irreversible erasure cost. A bounded informational load fraction is introduced together with a dimensionless latency potential, a covariant erasure source sector based on entropy-current divergence, and a phenomenological action whose terms are dimensionally consistent. Within this framework, inertia is reinterpreted as resistance to accelerated update demand; gravity emerges as a gradient in local latency; the Unruh temperature is read as the effective thermal signature of acceleration-induced informational reprocessing; black holes are treated as saturation-driven informational defragmentation zones; and late-time cosmic acceleration is modeled as an effective horizon-scale erasure sector. The theory is not proposed as a completed microscopic theory or as a replacement for established frameworks, but as a unified phenomenological and ontological scaffold linking information, thermodynamics, gravity, and cosmology. Mathematical structure, weak-field limits, field equations, cosmological embedding, interpretive scope, limitations, and possible routes toward empirical relevance are developed in detail.
