Category Mistakes in Quantum Gravity: Why Entanglement Cannot Generate Spacetime and the Case for Fluidodynamic Realism

Modern approaches to quantum gravity increasingly rely on information-theoretic abstractions—most prominently quantum entanglement—to construct or explain spacetime geometry (e.g., via the AdS/CFT correspondence and the ER = EPR conjecture). In this paper, we argue that elevating abstract statistical correlations in Hilbert space to physical metric fields represents an ontological category mistake. Furthermore, experimental programs aimed at proving the quantization of gravity via entanglement-induced interactions (such as QGEM protocols) conflate medium elastic response with quantum-geometric structure, adding unnecessary mathematical complexity without empirical necessity. As an alternative, we present a fluidodynamic framework (Time Bubble Universe, TBU) wherein gravity and metric properties emerge naturally from a continuous underlying substrate. By incorporating a physical microscopic cutoff scale rooted in the fluid's equation of state, the TBU framework eliminates gravitational singularities demonstrated via the regularization of the Kretschmann scalar with higher conceptual efficiency and fewer free assumptions than string-theoretic or loop models. Finally, we establish the observational bounds and stability criteria required for empirical falsifiability
