Observational Tests of the HRDCC Framework: Effective Cosmological Signatures from CMB to Next-Generation Surveys
Abstract
Modern observational cosmology is entering an era in which multiple high-precision surveys simultaneously probe the cosmic microwave background, the large-scale distribution of matter, the expansion history of the Universe, and the formation of the earliest astrophysical structures. While these observations provide increasingly stringent tests of cosmological models, they are often interpreted independently within separate phenomenological contexts. The present work examines these observational domains within the framework of the Holographic RotationDriven Cyclic Cosmology (HRDCC). Rather than focusing on individual anomalies or isolated observational signatures, the HRDCC framework is interpreted as an effective phenomenological architecture in which multiple cosmological observables originate from a common effective cosmological dynamics. This approach naturally motivates the interpretation of cosmic microwave background properties, large-scale structure, high-redshift galaxy formation, and future observational probes as correlated manifestations of the same underlying effective framework. Particular attention is given to observational strategies involving current and next-generation experiments, including Planck, DESI, Euclid, the Vera C. Rubin Observatory Legacy Survey of Space and Time (LSST), the James Webb Space Telescope (JWST), LiteBIRD, and PTOLEMY. The discussion emphasizes consistency between independent observational probes rather than isolated parameter fitting, highlighting how complementary datasets may collectively constrain or support phenomenological extensions beyond the standard cosmological model. The present paper therefore provides the observational synthesis of the HRDCC publication program by organizing the principal phenomenological predictions developed in the preceding papers into a unified observational framework. Within this perspective, the framework is intended to be evaluated through the overall consistency of multiple independent observational signatures rather than through any single observational discriminator. This manuscript constitutes the first paper of the HRDCC publication program. It is distributed as a preprint and has not undergone formal peer review.
