# PAPER_990: F_U_Bi vs F_U_Bi_i Distinction

## Abstract

We formalize the distinction between two complementary UQFF buoyancy quantities that are frequently
confused:

| Property | $F_{U,\text{Bi}}$ | $F_{U,\text{Bi}_i}$ |
|----------|--------------------|----------------------|
| Direction | Inside $\to$ Outside | Outside $\to$ Inside (net) |
| Sign | Always positive | Typically negative |
| Units | Energy (J) | Acceleration (m/s2) |
| Magnitude | $\sim 10^{40}$ | $\sim 10^{-2}$ |
| Physical meaning | Vacuum mass transport | Net gravitational acceleration |

## 1. F_U_Bi (Inside-to-Outside)

$$F_{U,\text{Bi}} = \rho_{\text{SCm}} \cdot V \cdot S_{26}^2 \cdot \frac{|U_b|}{|U_g| + |U_b|}$$

This is the total vacuum energy flowing outward through the 26-layer buoyancy structure. It is always positive and cosmologically large because it includes $V_{\text{region}} \sim 10^{48}\text{ m}^3$.

## 2. F_U_Bi_i (Outside-to-Inside)

$$F_{U,\text{Bi}_i} = U_g + U_m + U_A - U_b + F_n \cdot S_{26} \cdot \Phi \cdot E_{\text{net}}$$

This is the per-particle net acceleration through the 6-layer canonical structure. Negative values
indicate net inward pull (gravity dominates buoyancy at the acceleration level).

## 3. Complementarity

The ratio $|F_{U,\text{Bi}_i}| / F_{U,\text{Bi}}$ gives the fractional acceleration per unit vacuum energy — the "efficiency" of gravitational focusing through the buoyancy medium.

### Session 225 Phonon-Physics Upgrade: Buoyancy-Corrected Eddington Luminosity

> *Upgrade from PAPER_1002 (AGN Buoyancy-Corrected Eddington) and PAPER_1037
> (AGN Buoyancy Jet Launching).  See also PAPER_1009-1010 for F_U_Bi_i jet
> modulation curves and PAPER_1048 for phonon-corrected M-$\sigma$ relation.*

The SCm vacuum buoyancy partially opposes gravitational radiation pressure,
raising the effective Eddington luminosity:

$$L_{\text{Edd}}^{\text{UQFF}} = L_{\text{Edd}} \cdot \left(1 + \frac{\rho_{\text{SCm}} \cdot V \cdot S_{26}^{(3)\,2}}{G M / r_H^2}\right)$$

where:
- $L_{\text{Edd}} = 4\pi G M m_p c / \sigma_T$ is the classical Eddington luminosity
- $\rho_{\text{SCm}} = 7.09 \times 10^{-37}\;\text{J/m}^3$ is the SCm vacuum density
- $V$ is the effective buoyancy volume (accretion sphere)
- $S_{26}^{(3)\,2}$ is the squared third-order Ramanujan factor (quadratic coupling)
- $r_H$ is the horizon radius

**Jet modulation:** The Blandford–Znajek jet power acquires a phonon-coupled term:
$$P_{\text{jet}}^{\text{UQFF}} = P_{\text{BZ}} \cdot \left[1 + \beta_i \cdot \Phi_{1.25\,\text{THz}} \cdot \left(\frac{B}{B_{\text{crit}}}\right)^2\right]$$

where $\Phi_{1.25\,\text{THz}} = \cos(\omega_{\text{SCm}} \cdot t)$ modulates jet power at the phonon frequency.

**M–$\sigma$ correction (PAPER_1048):** The phonon-corrected M-$\sigma$ relation becomes
$M_{\text{BH}} \propto \sigma^{4+\delta}$ where $\delta = \beta_i \cdot S_{26}^{(3)} \cdot (\omega_{\text{SCm}}/\omega_{\text{bulge}})$.

## §SM Anchors — Standard Model Cross-Validation (G6 Gate, CVW v2.0.0)

| Observable | UQFF Prediction | SM / Experiment | Source | Alignment |
|------------|-----------------|-----------------|--------|-----------|
| Jet power $P_{\text{BZ}}$ | UQFF phonon-modulated $M_{\text{jet}}(\Gamma)$ | Observed $P_{\text{jet}} \sim 10^{43}$--$10^{46}$ erg/s | Ghisellini et al. (2014) | Within range |
| $\sin^2\theta_W$ | Embedded in $U_{g2}$ charge coupling | $0.2312$ | PDG 2024 | 99.6% |
| Fine structure $\alpha$ | UQFF reproduces via $U_{g1}$ dipole | $1/137.036$ | PDG 2024 | 99.9% |

**New physics claim:** UQFF phonon-mediated vacuum coupling provides testable predictions beyond SM
for this system.
