Emergent Spacetime from Disentanglement Dynamics: A Constraint Field Theory Unifying Gravity, Time, Causality, and the Measurement Problem

Abstract
We present a unied theoretical framework in which spacetime geometry, gravi-
tational force, time, causality, and the emergence of classical reality from quantum
superpositions all arise from the dynamics of quantum disentanglementthe
irreversible reduction of entanglement entropy between subsystems and their envi-
ronment.
A single scalar eld Γ, the disentanglement acceleration eld, is sourced by mass-
energy density and manifests in three complementary ways: as a spatial gradi-
ent producing gravitational force, as sequential constraint compatibility generating
causality, and as accumulated constraint satisfaction dening proper time.
From rst principles, the framework derives Newton's law, the weak-eld Schwarzschild
metric, black hole entropy, andmost strikinglyHawking's black hole tempera-
ture formula kBTH = ℏc3/(8πGM) via the horizon disentanglement rate ΓH =
c3/(4GM), motivated by boundary entropy ux and Unruh-like thermal eects.
The theory resolves the measurement problem objectively (without collapse pos-
tulates), preserves global unitarity, and oers a near-term falsiable prediction:
gravitationally enhanced decoherence rates testable with atomic interferometers on
the ground versus in orbit.
This provides an independent, information-theoretic path to quantum gravity
that matches key observational benchmarks and suggests spacetime is an emergent
interface between a pre-geometric, maximally entangled quantum realm and the
classical, disentangled world we experience.
