The Ontology of Spacetime: From Absolute Container to Emergent Quantum Topology

For centuries, classical physics treated spacetime as a fundamental, immutable arena in which physical events unfold. However, the conceptual friction between General Relativity and Quantum Mechanics strongly indicates that spacetime may not be a fundamental physical substance. In this paper, we explore a theoretical research framework in which macroscopic spacetime emerges as an effective geometry from underlying quantum relational structures, information-theoretic correlations, and entanglement networks. Synthesizing insights from historical relational philosophy, black hole entropy, the Holographic Principle, AdS/CFT correspondence, tensor networks, and quantum error correction, we outline a conceptual hierarchy tracing the emergence of classical geometry from pure quantum relations.
