<p>This work develops a unified cosmological and dynamical extension of Extended Classical Mechanics (ECM), demonstrating that the conventional speed of light (c) emerges not as an absolute universal limit, but as a stable manifestation boundary associated with the Planck-scale wavelength constraint (λ ≥ ℓᴘ) within the manifested physical regime.</p> <p>Within this framework, the luminal limit remains preserved under ordinary gravitationally bound conditions, where manifested matter mass dominates negative apparent mass. However, when the system transitions into a phase-dominated anti-gravitational regime, characterized by |Mᵃᵖᵖ| ≫ Mᴍ, the manifestation boundary weakens, permitting sub-Planckian wavelength contraction (λ &lt; ℓᴘ) and enabling superluminal phase propagation (vₚₕₐₛₑ &gt; c). This superluminality is interpreted not as a violation of known physics, but as a natural consequence of transition into an un-manifest phase regime where ordinary spacetime ceases to remain fundamental.</p> <p>The same formalism is shown to govern temporal emergence. Time is reinterpreted in ECM as an emergent consequence of phase-frequency transformation, distinguishing idealized clock time, event-driven cosmic time, and entropy-induced temporal distortion. This leads to a generalized concept of time distortion distinct from conventional relativistic time dilation.</p> <p>When extended cosmologically, ECM predicts a cyclic universe in which terminal cosmic evolution proceeds toward phase-dominated un-manifestation rather than thermal termination or infinite wavelength expansion. In this limit, the universe undergoes frequency-state reorganization, enabling re-manifestation and thereby providing a natural cyclic cosmology.</p> <p>This yields a structurally comparable but physically distinct alternative to Conformal Cyclic Cosmology (CCC), replacing conformal geometric continuity with phase-frequency continuity. ECM therefore provides a unified framework linking superluminal phase behavior, emergent time, and the cyclic fate of the universe within a single physical formalism.</p>
