Abstract We propose a two-component structure of physical time based on a distinction between Past-fixed (pf) and future-pending (fp) contributions. pf time encodes events that have already been realized and recorded, while fp time encodes those possibilities that have not yet become facts but may do so. This structure is represented by a complex-time variable and a normalized complex amplitude with , where pf and fp denote, respectively, the pf and fpcomponents. In this framework the imaginary unit is interpreted as a generator of rotations between pf and fp, rather than as a purely formal algebraic device. We show that unitary quantum dynamics can be understood as the conservation of the combined pf – fp weight, and that the Schrödinger equation describes rotations of the complex-time amplitude with angular velocity . Measurement processes are described as projections from fp to pf, and we argue that the Born rule arises from natural symmetry and additivity requirements on the frequencies of such future-to-past conversions. For two-level systems, equal fp alternatives lead to equal pf frequencies; for rational amplitude ratios, fp can be decomposed into equal “future packets” whose uniform projection into pf yields probabilities proportional to the squared amplitudes. In higher dimensions, Gleason’s theorem implies that these conditions uniquely single out the usual Born rule. We further show that discrete energy spectra can be viewed as a consequence of sampling the complex-time rotation only at those instants where lies on the real axis, , at which fp vanishes and the corresponding mode is fully pf. This leads to a quantization condition that reproduces Planck-type discrete energies for simple systems. Finally, we interpret tunnelling and evanescent domains as manifestations of fp structure: from the pf perspective an infinite barrier still enforces , but from the fp perspective a particle that has not yet appeared in that pf spacetime may exhibit fp amplitudes that transiently extend into the barrier region. Taken together, these results suggest that the imaginary unit can be interpreted as a “future factor” in quantum theory, and that a complex-time geometry provides a coherent route to connect quantum dynamics, probability, and discrete spectra with the temporal status of physical reality.

We present complex-time (CT) theory, a framework in which the fundamental structures of quantum mechanics are derived from three physical postulates concerning the internal structure of time. The postulates are: (P1) physical time possesses two orthogonal components — past-fixed (pf), representing actualized, irreversible records, and future-pending (fp), representing physically real but undetermined possibilities; (P2) pf and fp are orthogonal (pf fp); and (P3) the total temporal magnitude is conserved (pf + fp = 1). From these three postulates alone, we show that: (i) the state space is the unit circle and the dynamical group is , so that the imaginary unit arises as the unique generator of temporal evolution — not as a mathematical convenience but as a consequence of temporal geometry; (ii) the Schrödinger equation follows from the identification of energy with the rate of phase rotation in the pf–fp plane, with the Planck constant playing the role of a natural constant intrinsic to the pf/fp structure; (iii) the de Broglie–Einstein relation holds universally — for massive and massless particles alike — because the wave structure belongs to time itself, not to any particular particle; (iv) the uncertainty principle is a geometric consequence of the impossibility of fully eliminating fp while preserving ; (v) the complex structure of Hilbert space, the inner product, and the Born rule all follow from the geometry of fp pf projection; and (vi) energy quantization emerges from a “real-axis sampling” rule without imposing discreteness on the underlying dynamics. We further show that the CT framework provides unified descriptions of double-slit interference, quantum tunneling, unstable-state decay widths, and the structural origin of the arrow of time. Preliminary experimental predictions for quantum-circuit observables are stated, and applications to cosmological dark-energy phenomenology, galaxy rotation curves, and Lorentzian path-integral contour selection are outlined with references to dedicated companion papers. The central thesis is that quantum mechanics is not a theory of particles with mysterious wave-like properties, but a consequence of the internal structure of time — time whose wave-like phase (fp) is projected, irreversibly and discretely, onto the real axis (pf) in every act of measurement.

Abstract We introduce a complex-time framework in which the imaginary unit i is interpreted not as a formal algebraic device but as the generator of a physically meaningful temporal transformation. In this formulation, time is represented as a complex quantity T = pf + i·fp with |T| = 1, where pf (past-fixed) denotes the real component representing actualized, recorded history, and fp (future-pending) denotes the imaginary component representing undetermined possibilities. The constraint |T| = 1 expresses conservation of total temporal magnitude: as possibilities are determined (fp decreases), actualized history accumulates (pf increases). Temporal evolution is described by continuous rotation in the complex-time plane, governed by dT/dθ = iT, while a non-Hermitian extension dT/dθ = iT − γT (γ > 0) describes dissipative processes and the emergence of the arrow of time. Within this framework, quantum measurement is identified with a discrete, irreversible real-axis projection—the conversion of fp into pf—that constitutes a single step of time’s advance from the imaginary to the real axis. This identification yields three concrete predictions for quantum circuits: (i) measurement-induced effects depend on measurement count M rather than free-evolution time T (T-independence); (ii) irreversibility accumulates linearly with M in time-reversal protocols; and (iii) the elementary duration δ of one real-axis projection is implementation-dependent. The framework provides a unified structural basis for the continuity of motion, quantum uncertainty, and macroscopic irreversibility, suggesting that these phenomena arise from a single generative process: the continuous, irreversible conversion of future-pending structure into past-fixed record.

Abstract This study introduces a complex-time structure in which the imaginary unit i is interpreted not merely as an algebraic constant but as a possible generator of temporal transformation. Within this formulation, time may emerge from a continuous rotation between two complementary domains of reality—the future-pending (fp) and past-fixed (pf)components. Such rotation provides a potential structural basis for three fundamental aspects of nature: the continuity of motion, quantum uncertainty, and macroscopic irreversibility. Mathematically, the temporal variable satisfies analogous to the unitary generator in quantum mechanics, while a non-Hermitian extension (with γ > 0) may describe dissipative processes and the emergence of the arrow of time. The imaginary component i can therefore be viewed as mediating the transformation from potential to realized states, offering a structural link between microscopic reversibility and macroscopic asymmetry. Recent experiments highlighting the indispensable role of complex numbers in quantum mechanics [1] are consistent with this perspective. Possible verification strategies—such as complex-phase interferometry, delayed-choice erasure, and quantum-simulation approaches—are briefly outlined as potential probes of i-mediated temporal dynamics. Overall, this work suggests that the complex-time structure may provide a coherent physical framework in which time, uncertainty, and irreversibility arise from a single continuous generative process.

Abstract This study extends the complex-time framework introduced in Part I, where time was formulated as an intrinsic complex coordinate . Within this framework, the imaginary unit is reconsidered not as an algebraic symbol but as an operator of indeterminacy, representing the undetermined future phase of physical existence.The real component corresponds to the determined past. Temporal evolution is thus interpreted as a continuous projection through which potential states become actualized. Building upon this model, we propose a unified interpretation of measurement, entropy, entanglement, and nonlocality. Measurement may be viewed as a temporal projection fixing latent existence from the imaginary phase into the real domain; entropy growth corresponds to the cumulative conversion of undetermined futures into fixed pasts, giving rise to the arrow of time. Quantum indeterminacy is reinterpreted as the openness of the future, while entanglement appears as a form of temporal coherence connecting events through a shared phase structure. When correlations become fully realized, the internal -phase vanishes and the relation attains , implying a null-temporal state beyond spacetime separation. At the macroscopic level, matter with rest mass can be regarded as a dense network of such microscopic fixations. Each quantum interaction functions as a micro-instance of temporal fixation, producing the statistical rhythm perceived as continuous time. This interpretation suggests that reality may evolve through a self-referential process in which the universe continuously projects its potential phase into realized history—a dynamic structure of physical reality emerging from complex-time geometry.

Description / Abstract English version (recommended for main entry): Time in physics has long been treated as an external, passive parameter.However, such a conception fails to explain why motion is continuous and why the past and future are asymmetric.This paper reformulates time as a complex rotation, in which the imaginary unit i acts as the generator transforming future-pending (fp) states into past-fixed (pf) states.Expressed as T=pf+i fp=eiθ,T=pf+ifp=eiθ, this framework interprets temporal evolution as the rotation of existence itself.By connecting this model to the uncertainty principle[x^,p^]=iℏ[x^,p^]=iℏ,the paper shows that i represents the physical mechanism underlying noncommutativity, continuity, and irreversibility.Applied to Zeno’s paradox, the introduction of a complex phase allows the “arrow” to acquire motion and pierce the target, resolving the classical problem of infinite division.Furthermore, the cumulative, immutable nature of pf-states suggests a blockchain-like temporal structure, explaining why the past cannot be altered and why time’s arrow cannot reverse.This complex-time geometry unifies quantum indeterminacy, temporal continuity, and informational irreversibility within a single conceptual framework.

Quantum mechanics is built on the imaginary unit i, yet it does not say what that i physically is, and it treats time as an external parameter without internal structure. This paper places a single identification: time is a unit complex quantity with two orthogonal components, T = pf + i·fp (|T|² = 1), where pf is the fixed past, fp is the undetermined future, and i is the generator of the 90° rotation between them. From this identification, with the additional inputs counted explicitly (linearity of the evolution, inertial-frame invariance of the internal frequency, and local phase invariance), follow the structure of the Planck relation (E ∝ ω, amplitude-independent), the Schrödinger equation, the metric of special relativity and its signature, the electromagnetic gauge structure, the form of the Born rule, and the skeleton of the Dirac equation. Three consequences about time follow. First, "time" is two-layered: the rotating hand (the internal phase time T, which ticks proper time) and its winding number (the parameter time t). Second, the rate of the proper clock is an invariant of the worldline; observer-dependent energy cannot drive it; the clock is driven only by the invariant of the dispersion relation, the mass squared m². A state with non-positive m² becomes a "frozen envelope": it stores configuration energy while its proper phase does not rotate (the dynamics of its stability is disclosed as an open seam). Third, the arrow of time sits not in dynamics but in a modal asymmetry (undetermined → fixed). Around the threshold m² = 0 these consequences become distinguishable from the standard theory, and they connect to three companion papers: neutrinos (residents of the threshold), dark energy (the allocation of the cosmic phase), and dark matter (stranded states that failed ignition).
