=== These are real, known physical effects you can legitimately use in QAT: ===
# Radiation pressure & Poynting–Robertson drag. Photons impart momentum and cause orbital decay of dust; this is real and well understood — it’s small but directional and can mimic “inward drift” in certain frames.
# Van-der-Waals / Casimir attractions. Exchange of virtual photons and correlated fluctuations produces forces between neutral bodies; these are quantum EM effects, sometimes appearing as attractive forces at short range (not 1/r²).
# Bound EM energy contributes to inertial/gravitational mass. In a composite system, binding energy changes total mass (E/c²). That’s consistent with GR but numerically small compared to rest masses of macroscopic bodies: binding energy is significant for nuclei but tiny for neutral macroscopic matter.
# Optical metric / Gordon metric. Light in a dielectric medium sees an effective metric; coherent EM structures can modify light propagation as if space were curved. This shows how EM + medium can mimic some geometric effects.
# Induced gravity / Sakharov: quantum vacuum fluctuations and the response of matter fields can induce an effective gravitational action (Einstein–Hilbert) when modes are integrated out. This is promising for QAT-style emergence but technical: the induced Newton constant usually depends on cutoff and high-energy details.
