To explore how gravitational dynamics can arise from thermodynamic responses at boundaries within an effective field theory framework.
Developed an effective field theory based on boundary degrees of freedom.
Utilized the Dirichlet-to-Neumann operator to analyze boundary responses to bulk perturbations.
Derived MOND acceleration scaling from the connection between local and cosmic thermodynamics.
Estimated MOND acceleration a₀ ≈ 1.3 × 10⁻¹⁰ m/s², which aligns with observational data within ~10%.
Provided a relationship linking the cosmological constant to the acceleration scale.
Proposed falsifiable predictions including a universal acceleration a₀ across different galaxies.
