Abstract
<jats:p>Abstract. This work proposes a cosmological framework for the origin of space-time. The framework unifies several major cosmological phenomena, including redshift, cosmic expansion, gravitational effects, and the evolution of celestial objects. It provides a consistent physical interpretation for the origin and expansion of the universe, and offers testable observational predictions related to astronomical measurements such as the James Webb Space Telescope, Euclid and LISA. The model classifies cosmic objects and describes their evolutionary pathways, while also offering a new explanatory mechanism for quantum entanglement and gravitational lensing. It further establishes a unified interpretation of type Ia supernovae and gravitational lensing within the same theoretical system. The framework distinguishes itself from conventional ΛCDM cosmology and supplies new constraints for ongoing astronomical observations. It treats cosmic expansion not merely as kinematic motion of galaxies, but as an intrinsic structural evolution of spacetime itself. This perspective naturally avoids some fine-tuning challenges present in standard cosmology and opens new directions for connecting large-scale cosmic dynamics with fundamental quantum behaviour. This manuscript lays out the core physical framework of the model and its associated observational predictions; follow-up studies will elaborate on individual subtopics in separate contributions.</jats:p>
