A Conceptual Framework for Emergent Spacetime

We present a speculative but structured cosmological framework in which visible matteris not taken to be the primary substance of the universe, but rather a later thermalbyproduct of an earlier and more fundamental dark-sector evolution. The central idea isthat spacetime itself emerges from an initially undifferentiated primordial state, after whichthe components later interpreted as dark energy, dark matter, and geometric gravity differentiateas effective modes of that unfolding. As the universe expands and cools, the thermaland configurational state of the underlying sector changes, potentially inducing transitionsin the effective behavior of gravity and dark matter before the visible sector appears throughstandard symmetry-breaking and confinement processes. We organize the proposal aroundcore postulates, temperature-ordered cosmological checkpoints, energy-density bookkeeping,entropy-based interpretation, and a minimal mathematical language suitable for future refinement.The paper is intended as a conceptual framework rather than a completed theory;explicit dynamical equations, ultraviolet completion, and observational tests remain to bedeveloped.
