Holographic Rotation-Driven Cyclic Cosmology (HRDCC): A Unified Dynamical Framework for Cyclic Cosmology

We present Holographic Rotation-Driven Cyclic Cosmology (HRDCC), an effective cosmological framework in which cosmic evolution is governed by the coupled dynamics of holographic information, rotational degrees of freedom, and successive cosmological cycles. Rather than treating cosmological expansion, black-hole physics, and the large-scale evolution of spacetime as independent phenomena, the framework interprets them as different manifestations of a common effective dynamical process. The framework assumes that each mature cosmological cycle originates through a nonsingular cosmological transition associated with gravitational collapse inside a parent black hole. Physical continuity between successive cosmological cycles is maintained through the regularized Holographic Transition Core (HTC), while inherited rotational degrees of freedom contribute to the effective cosmological dynamics. Within this phenomenological description, the effective cosmological components associated with dark matter, dark energy, and the late-time accelerated expansion of the Universe emerge naturally from the long-term cyclic cosmological evolution rather than being introduced as independent fundamental constituents. An effective dynamical formulation is developed by extending the standard Friedmann background with phenomenological contributions associated with the HTC, inherited rotational dynamics, and the effective cosmological components. The resulting framework remains compatible with the established large-scale phenomenology of standard cosmology while providing an alternative physical interpretation of the origin of cyclic evolution, cosmological initialization, and the dark sector. The HRDCC framework generates a set of potentially testable observational signatures involving large-scale anisotropies, rotational effects, gravitational-wave propagation, black-hole populations, and the long-term evolution of the dark sector. These predictions provide possible observational discriminants with respect to the standard ΛCDM cosmology and other cyclic cosmological scenarios. The present work establishes the conceptual foundations, effective mathematical formulation, and principal physical implications of the HRDCC framework. Detailed microscopic mechanisms, including Planck-remnant dark matter, black-hole interior dynamics, primordial perturbations, numerical cosmological evolution, and quantitative observational constraints, are addressed in dedicated subsequent papers within the HRDCC publication program.
