This article proposes a new theoretical model that combines spatial and temporal dynamics, which has a normalized form of the basic equation: v c 2 + u t 2 = 1 where: c is the invariant speed c, commonly associated with light propagation in vacuum, is reinterpreted here as a fundamental bound representing the completeness of an existential state. Its constancy reflects preserving existential integrity, independent of local spacetime variations or temporal symmetry violations. As such, c defines the upper norm of the existential motion vector, beyond which no evolution can occur. u t is the temporal velocity; u t introduced in this model, emerges from quantum localization and defines a dimensionless scalar confined to the interval [0,1]. v is the spatial component of motion; v is normalized by the invariant speed c, yielding the dimensionless ratio v c. In conjunction with the dimensionless temporal metricu t , this framework preserves unit consistency and formally integrates spatial and temporal domains into a single invariant relation. In this model, the emergence of complexity in the Universe results from the local stabilization of the temporal metric u t. Stable structures arise in regions whereu t t maintains coherence within defined thresholds, allowing the formation of molecules, cells, and higher-order material organizations. Coherence inu t enables resonance among system components, serving as a fundamental condition for structural sustainability. Critically, the model extends this framework to consciousness, proposing that u t underlies its formation. The reciprocal embedding of consciousness and u t provides the basis for the following formalization. r = C (R, H, u t) where C is a modification operator described as C (r) = K (r, ξ, t, u t) where: A PREPRINT-MAY 9, 2025 • R (Reality): the objective substrate of existence. • K (Kernel of Transformation): an integral operator that transforms subjective knowledge based on the current state of consciousness and contextual variables ξ, time t, and temporal velocity u t ; formally, K(r, ξ, t, u t). • ξ: a vector of contextual parameters, including sensory input, associative states, and cultural priors; i.e., K (r, ξ, t, u t)-the core that models the influence of a specific context ξ on the processing of subjective knowledge r; • r (Reflection of reality): the subjective representation of R. • C (Consciousness): a nonlinear operator acting on contextual fields, modulating the system's trajectory within a potential landscape H. • H (Chaos): a field of potential trajectories (structured uncertainty) that enables optimization of temporal participation through contextual resonance; chaotic fluctuations play the role of a "sensory space" that allows the system to adapt and refine itself u t by changes in the environment constantly. • t: the local temporal parameter defining the point of integration in conscious transformation. • u t (Temporal Velocity): a dimensionless scalar regulating the epistemic relevance of knowledge at the moment of cognition. The proposed model reconceptualizes time not as the fourth coordinate of classical space-time or a mere quantitative axis (e.g., elapsed seconds) but as the intensity of existential presence. Through the temporal metric u t , time acquires a functional role in determining the degree to which a system particularly a conscious one-participates in being. Rather than passively measuring duration, time operates as a dynamic parameter in realising existence. This framework extends conventional physical theory by integrating cognitive dimensions into space-time structure, offering a unified account of temporality and consciousness. The model further outlines potential applications in artificial intelligence, medicine, and biology. SUMMARY. Time is reinterpreted as a form of velocity u t , quantifying the degree of existential participation in physical reality rather than measuring abstract duration. The model unifies motion, cognition, and structured chaos within an ontological framework anchored in observable reality and bounded by physical invariants.
