Contemporary physics increasingly suggests that spacetime, geometry, and even fundamental interactions may not be primitive constituents of nature but emergent structures arising from deeper informational or topological organization. Motivated by developments in entanglement-based emergent gravity, topological quantum field theory, and operator-algebraic approaches to quantum theory, this article proposes an information-theoretic and topological framework in which physical law arises from entropy-weighted projections on a diagrammatic Hilbert space. The aim is not to present a fundamental physical theory, but to articulate a coherent conceptual architecture clarifying how informational constraints, topological equivalence classes, and operator structures can jointly underpin geometric and dynamical regularities. A diagrammatic Hilbert space encodes possible topological configurations; an entropy functional over these structures defines a rule of informational preference; and entropy-weighted projection operators implement a form of epistemic coarse-graining that—when iterated across scales—gives rise to geometric, gauge-like, and dynamical structures through the algebra of commutators. We situate the proposal within the existing philosophical and scientific literature on emergence, information, and the ontology of spacetime, emphasize its conceptual motivations, and delineate the implications for the status of laws and physical modality. While speculative in scope, the framework is intended as a structured conceptual contribution to foundational discussions about the possible informational origin of physical law.
