A Note on Why the "Speed of Time" Is Conceptually Meaningless — Time as Information Accessibility

Revised Abstract (V2) This note clarifies a conceptual foundation underlying the Temporal Membrane Theory by examining the meaning of time from the perspective of information accessibility rather than temporal flow. We argue that the notion of a “speed of time” is fundamentally ill-defined, as it inevitably reduces to a self-referential expression. Instead, time is reinterpreted as a relational structure that enables or restricts the transmission and reconstruction of information. Within this framework, observable temporal effects do not arise from variations in the progression of time itself, but from geometric distortions in the accessibility of information across spacetime. Regions that are causally disconnected do not share an observational time structure, even though local physical processes may persist. The relation to general relativity is clarified as follows. Gravitational time dilation as described by general relativity correctly accounts for changes in the rates of local physical processes, such as particle dynamics and electromagnetic interactions. The present framework does not modify or contradict this description. Rather, it addresses an additional observational layer: systematic residual delays that arise from distortions in the transmission and reconstruction of temporal information. These effects manifest as deviations relative to the temporal structure predicted by general relativity, without implying any failure of the theory itself. This document serves as a conceptual and philosophical foundation for the Temporal Membrane Theory and is provided as a theoretical memorandum for the purpose of obtaining a DOI; it does not constitute a complete physical paper nor is it intended for journal submission.
