Invariant Temporal Ordering Framework V36/F16: Universal Cosmic Extension, Common Cosmic Change Stages, and System-Specific Physical Change

The Invariant Temporal Ordering Framework V36/F16 presents a foundational account of time that separates temporal identity from the physical and mathematical means used to measure, represent, or calculate change. It defines time as the one universal cosmic extension of common cosmic change stages, constituted by their invariant universal earlier–later ordering and succession. This extension is not a physical substance, field, force, container, metric duration, coordinate interval, or moving carrier. It is the common ordered extension within which the physical histories of all qualified systems are realized. The framework assigns different roles to temporal order and physical change. The common cosmic change stage is universal, while the physical change realized at that stage belongs individually to each physical system. The Cosmic Moment Axiom states that the complete qualified population of physical systems then existing in the universe is realized at literally the same objective common cosmic change stage. Universal Change Continuity independently requires every such system to undergo its own system-specific physical change throughout its realized identity history. The unity is therefore unity of stage, not uniformity of physical state, mechanism, magnitude, rate, causal process, or observational outcome. V36/F16 further states that the universal cosmic ordering is strict and irreversible. A later stage remains later even if a system later returns to a physical condition similar to an earlier one. Under the separately adopted NoInterruption and NoTerminalStage commitments, the cosmic succession is uninterrupted and continuing, without introducing metric continuity, equal stage spacing, numerical temporal intervals, or a final cosmic stage. Every physical system has an identity-bounded physical history within the same universal cosmic extension. Systems may begin, develop, transform, and end at different common stages without acquiring private times. Physical history belongs to the system; time remains common. The framework also distinguishes earlier realized physical history from the effects of that history that remain embodied in a later physical condition, and it separates identity ending from successor production so that the end of one system does not automatically require the formation of another. Observation and measurement are treated as physical processes rather than direct access to temporal identity. A valid record may establish or quantify a physical manifestation without identifying the exact common cosmic change stage at which that manifestation was realized. First detection is therefore an observational threshold rather than the beginning of physical change. Clocks are treated as physical systems producing operational records, not as embodiments of time itself. This distinction is generalized through the Non-Transfer Principle: mathematical consistency, physical realization, operational usefulness, or predictive success do not by themselves transfer temporal identity to a coordinate, metric quantity, clock output, model variable, or other scientific object. On this basis, V36/F16 directly rejects the identification of time with relativistic coordinate time, proper-time functionals, metric intervals, frame-dependent simultaneity relations, spacetime metrics, or clock outputs, while distinguishing that ontological disagreement from the separate empirical question of how successfully particular physical models predict observations. V36/F16 therefore presents time as universal temporal unity without physical uniformity: one invariant cosmic extension and ordering, one common stage for the entire then-realized physical population, and many distinct system-specific physical changes and histories realized within it.
