The Singularity Substrate: Emergence of Spacetime from an Information-Theoretic Substrate via Quantum Measurement

We propose a theoretical framework where spacetime emerges from quantum measurement dynamics within a universal information-theoretic substrate, modeled by a vector field ⃗Ψ. The theory incorporates causal Lindblad decoherence, gauge-invariant Higgs coupling, and entanglement-driven gravity via the replica trick. We derive the entropy-area relation from first principles and connect decoherence rates to Higgs mass fluctuations. Experimental falsifiability is outlined through cosmological and quantum device signatures.
