A formal formulation of the concept of structural order of the vacuum is proposed as a dynamic foundation prior to observable physical time. A non-metric precedence relation is introduced that allows defining the coherent composition of quantum operators without presupposing a fundamental temporal parameter. Physical time emerges as an effective projection associated with macroscopic observables, irreversibility, and accessible information. The formalism is compatible with standard quantum mechanics and quantum field theory, reinterpreting the temporally ordered product as a particular case of a deeper structural order.

This paper develops a consistent and self-contained formulation of external (physical) time as an emergent quantity, arising from the internal temporal evolution of correlational sites within the Universal Correlational Lattice (UCL) framework. Rather than assuming time as a fundamental background parameter, the theory distinguishes between: Internal times, defined locally at each correlational site through intrinsic dynamical evolution, and External time, which emerges relationally from the synchronization, ordering, and stability of correlations among multiple sites. The work formalizes how a coherent, observer-independent notion of temporal flow can arise without postulating a pre-existing global clock. External time is shown to correspond to a coarse-grained, effective parameter that captures persistent, ordered correlations across the correlational network, while remaining compatible with regimes where no global time is well-defined. Key results include: A precise definition of temporal evolution along internal time without reference to external time units. The emergence of a one-parameter effective temporal ordering from correlational dynamics. A clear separation between pre-geometric (timeless or multi-temporal) regimes and geometric regimes where an effective spacetime description becomes valid. Conceptual and mathematical consistency with relativistic causality, decoherence, and macroscopic temporal stability. This framework provides a natural resolution to longstanding tensions between quantum theory and general relativity regarding the status of time, without invoking collapse postulates or external observers. Time is not fundamental, but real and physical as an emergent, relational structure. The paper is intended for researchers interested in foundational questions of time, quantum gravity, emergent spacetime, and relational approaches to physics.
Abstract The physical status of time remains one of the most persistent open questions in fundamental physics. In quantum mechanics, time appears as an external parameter governing evolution but not as an observable, while in general relativity it is embedded in the geometric structure of spacetime and becomes observer-dependent. Despite their empirical success, neither framework explains the physical origin of time or its singular role among fundamental quantities. In this work, we propose an emergent interpretation of physical time grounded in quantum phase. Phase is treated as a pre-temporal structural feature of quantum systems, rather than as a quantity defined with respect to an underlying temporal parameter. Energy is interpreted as a relational characterisation of regularities in phase structure, and proper time emerges only in contexts where phase accumulation can be compared and synchronised between interacting systems. An isolated quantum system may possess phase, but it does not possess physical time in the operational sense; time arises only through relational compatibility. This approach does not introduce new fundamental dynamics nor posit a physical mechanism responsible for the generation of time. Instead, it establishes an ontological hierarchy in which phase is fundamental, energy is relational, and time is a phenomenological quantity that emerges from stable conditions of synchronisation. Within this framework, classical reality corresponds to domains of temporal compatibility, while loss of compatibility underlies the emergence of horizons and geometric structure. By reframing time as an emergent relational phenomenon rooted in quantum phase, this work provides a coherent interpretative framework in which the absence of a time operator in quantum mechanics and the difficulty of quantising time and gravity are understood as consequences of their non-fundamental status, rather than as shortcomings of existing formalisms.
Abstract This article presents a revised and conceptually refined formulation of a previously proposed Temporal Interpretation of quantum measurement, explicitly addressing the physical nature of wavefunction collapse. While the original proposal emphasised relativistic aspects of momentum superpositions, the present work clarifies the interpretation within the standard formalism of quantum mechanics, without introducing new dynamics or experimental predictions. Unitary evolution is read as a process of differentiated phase accumulation between branches of a quantum state. In relativistic contexts, phase differentials can be structurally related to effective proper-time differentials, allowing the introduction of a notion of temporal compatibility that provides a physically grounded account of decoherence. When such differentials exceed a characteristic scale, interference between branches becomes operationally inaccessible, while global unitarity is preserved. The observer is treated as a physical system endowed with an irreversible proper time associated with macroscopic, entropic dynamics. Within this framework, collapse is explained as an emergent physical phenomenon arising from the irreversibility of the observer’s proper time, which prevents the reconstruction of phase coherence after an interaction. Collapse is therefore neither a fundamental dynamical mechanism nor an objective event in space-time, but a necessary consequence of temporal irreversibility in physical observers. This formulation sharpens the distinction between decoherence and collapse, preserves full consistency with the Born rule, and positions the Temporal Interpretation as a competing interpretative framework that provides a concrete physical explanation for the quantum–classical transition, improving and clarifying the original proposal. This version clarifies the operational status of the interaction time, refines Sections 5.3 and 5.4, and standardises references and editorial structure. No changes to the formalism or conclusions.
Abstract The ontological status of time remains unresolved in fundamental physics. In quantum mechanics, time appears as an external classical parameter, whereas in general relativity it is dynamical and intertwined with spacetime geometry. Canonical approaches to quantum gravity, most notably the Wheeler–DeWitt formulation, eliminate time altogether, leading to the well-known “problem of time.” These tensions motivate frameworks in which time is not fundamental but emergent. In this work, we propose a discrete, update-based framework in which the universe evolves through a sequence of global quantum states indexed by an abstract update parameter rather than by a physical time coordinate. Evolution is formulated as a completely positive, trace-preserving (CPTP) quantum channel acting on the universal density operator, ensuring exact conservation of probability and global quantum information at every update. The framework is deliberately conservative: it preserves the formal structure of quantum mechanics and quantum field theory, enforces vacuum stability, and supports global conservation laws without introducing new dynamical postulates. Within this setting, time emerges relationally at the level of subsystems. As subsystems become increasingly entangled with their environments, entropy gradients arise that define an effective arrow of time, closely aligned with the thermodynamic arrow. The resulting temporal flow is relative, statistical, and observer-dependent, while the global evolution remains information-preserving and, in the closed-system limit, reversible. We explore the implications of this framework for cosmology and black hole physics. The Big Bang is reinterpreted as an initial quantum state rather than a singular beginning of time, avoiding temporal singularities. Black hole evaporation is shown to be compatible with unitary evolution when the full quantum state is considered, naturally reproducing the expected Page curve and resolving the apparent information paradox. Overall, the framework provides a coherent, minimal setting in which time, irreversibility, and cosmological history emerge from quantum correlations rather than from a fundamental temporal background.
The nature of time remains a central problem in fundamental physics, spanning quantum mechanics, thermodynamics, and relativity. In this work, we develop an observer-dependent framework in which time is not assumed as a fundamental background parameter, but emerges operationally from restricted access to a globally timeless quantum state. Building on and extending the Page–Wootters mechanism, we introduce a unified relational formula that shows how three traditionally distinct aspects of temporality arise from the same structure: quantum dynamics from conditioning on physical clock states, thermodynamic irreversibility from partial tracing over inaccessible degrees of freedom, and observer-relative time from the locality of the clock subsystem. No modification of unitary quantum mechanics, collapse postulates, or fundamental time flow is required. Analytical arguments and numerical simulations demonstrate that, in the limit of complete information access, all temporal ordering disappears, while effective Schrödinger dynamics and an arrow of time emerge naturally under informational and observational constraints. These results support a central claim: time is not a property of the universe itself, but a property of descriptions generated by physical observers embedded within it.
Understanding whether the mathematical structure of quantum mechanics is fundamental or emergent remains a central question in the foundations of physics. In particular, the special role played by time in quantum theory, appearing as an external evolution parameter rather than a dynamical observable, suggests that the formalism itself may arise from deeper structural considerations. In this work, we investigate the emergence of quantum mechanical formalism from classical wave dynamics by adopting a dimensional framework in which time is treated as a +1 evolution parameter relative to the dimensions through which physical phenomena (fields or disturbances of a field) propagate and interact. Within this perspective, different fields may evolve with respect to different effective dimensions, while remaining embedded in a common higher-dimensional space, allowing time to acquire a relational and context-dependent role. This means that in our proposed model, time is not a fixed dimension which is experienced the same way for every field or field interaction of any dimensionality. In that sense, time for one physical phenomenon can behave as space for a higher dimensional physical phenomenon, whose time is a different +1 dimension. The central objective of this paper is to determine how a higher-dimensional deterministic field can be consistently represented by a lower-dimensional description that lacks direct access to its full set of evolution parameters and evolves through a spatial (for the higher-dimensional field) dimension. To this end, we introduce a general projection framework in which a higher-dimensional field is mapped to a reduced field through an interaction-based recording process. Crucially, we do not assume the form of this mapping a priori. Instead, we impose the requirement that it preserve the maximum amount of physically accessible information. In particular, we demand the faithful encoding of phase relations, interference structure, and spectral composition, including the relative contributions of different Fourier modes and their superposition. We first demonstrate, within a purely classical 3+1-dimensional wave framework that these constraints severely restrict the admissible form of the reduced description and naturally lead to complex amplitudes, linear superposition, Hilbert space structure, and canonical operator relations. This analysis provides an intuitive and mathematically explicit route to quantum-like descriptions without assuming quantum postulates. We then generalize the construction to a 4+1-dimensional framework, introducing an additional evolution parameter and showing that under the same information-preserving constraints, the Schrödinger equation appears as an effective low-energy description of the reduced dynamics, while a relativistic dispersion relation emerges simultaneously through the encoding of the hidden evolution parameter as an invariant frequency scale. In this way, both quantum mechanical and relativistic structures arise from the same underlying requirement: the consistent and information-preserving representation of higher-dimensional wave propagation in a lower-dimensional observational framework. The results suggest that the formal structure of quantum mechanics need not be postulated a priori, but may instead be understood as the unique mathematical language required to encode the observable remnant of a higher-dimensional deterministic dynamics under strict constraints of symmetry, invariance, and information preservation.
