===== Problem: If ongoing radiation power sets gravity, hotter bodies (more radiation) should weigh measurably more. Real experiments show no practical change (temperature-dependent mass differences are negligible, consistent with Δm=ΔE/c2\Delta m = \Delta E/c^2Δm=ΔE/c2). =====

Numbers: Earth’s ambient thermal energy density is tiny relative to rest mass: at 300 K, blackbody energy density u∼aT4≈6×10−6 J/m3⇒u/c2∼6×10−23 kg/m3u\sim aT^4 \approx 6\times10^{-6}\ \mathrm{J/m^3}\Rightarrow u/c^2\sim 6\times10^{-23}\ \mathrm{kg/m^3}u∼aT4≈6×10−6 J/m3⇒u/c2∼6×10−23 kg/m3. That is negligible compared with mass densities.

Rescue path: QAT must show that it is not net emitted thermal radiance per se that sources gravity, but rather coherent or boundary-constrained exchange that contributes to the effective mass (e.g., standing wave energy, bound field energy). Bound energy already contributes to mass in GR (binding energy changes mass) — this matches QAT if you can show boundary events generate bound energy without net radiation loss.
