## Abstract

$$\rho_{\text{vac}} \in \{7.09 \times 10^{-37},\ 7.09 \times 10^{-36},\ 2.84 \times 10^{-36},\ 10^{-23},\ 8 \times 10^{-21}\}\ \text{J/m}^3$$

The UQFF Vacuum Density Series (VDS) is a multi-scale logarithmic scaffold of vacuum
energy densities representing distinct layers of the Universal Aether (UA) medium. Five
primary density values span sixteen orders of magnitude, from the [SCm] superconductive
vacuum (7.09$\times$10-37 J/m3) to the solar wind vacuum (8$\times$10-21 J/m3), with the fundamental
Aether baseline at 10-23 J/m3 (= 10-20 kg/m3). An extended series from Aether13_16
spans 77 orders from proton volume (10-39 cm3) through the universe mass (1054 gm),
providing the density anchor chain for all UQFF gravity, buoyancy, and inertia equations.
Each density level supports a distinct gravitational and electromagnetic mode, enabling
the discrete banding of Universal Gravity ranges Ug1--Ug4.

## §1 The Vacuum Density Layers

### 1.1 Primary UQFF Vacuum Density Series

| Layer | Symbol | Value | Physical Domain |
|-------|--------|-------|-----------------|
| [SCm] superconductive | $\rho$vac,[SCm] | 7.09$\times$10-37 J/m3 | Extra-universal conductive medium |
| Universal Aether [UA] | $\rho$vac,[UA] | 7.09$\times$10-36 J/m3 | Primary gravitational medium |
| Universal Inertia | $\rho$vac,Ui | 2.84$\times$10-36 J/m3 | Inertial modulation layer |
| Aether baseline | $\rho$vac,A | 10-23 J/m3 | Cosmological vacuum floor |
| Solar wind | $\rho$vac,sw | 8$\times$10-21 J/m3 | Stellar heliospheric boundary |

The ratio $\rho$vac,[SCm] / $\rho$vac,[UA] = 0.1 is the fundamental suppression factor entering the Ui, Ug2,
and Ereact equations.

The reactor efficiency factor encodes the full series:
$$E_{\text{react}} = \frac{\rho_{\text{vac},[SCm]} \cdot v_{SCm}^2}{\rho_{\text{vac},A}} \cdot e^{-\kappa t} \approx 10^{46} \cdot e^{-0.0005t}$$

where $\kappa$ = 0.0005 day-1 is the [SCm] reactivity decay rate.

### 1.2 Extended Cosmological Series (Aether13_16)

| Quantity | Value | Scale |
|----------|-------|-------|
| Planck length | 1.616$\times$10-35 m (= 1.616$\times$10-33 cm) | Minimum spatial resolution |
| Proton volume | ~10-39 cm3 | Nuclear UQFF density anchor |
| Nuclear volume energy | ~10-35 gm | Nuclear-scale density |
| Vacuum density of space | 10-23 gm/cm3 = 10-20 kg/m3 | Cosmic Aether baseline |
| Universe mass | ~1054 gm | Total cosmological energy content |

**Density range spanned:** 10-39 cm3 (proton volume) $\leftrightarrow$ 1054 gm (universe mass) $\to$ 93 orders total.

### 1.3 Physical Interpretation of the Ratio Chain

$$\frac{\rho_{\text{vac},[SCm]}}{\rho_{\text{vac},[UA]}} = 0.1 \quad \Rightarrow \quad \frac{\rho_{\text{vac},[UA]}}{\rho_{\text{vac},A}} = \frac{7.09 \times 10^{-36}}{10^{-23}} = 7.09 \times 10^{-13}$$

This 13-order-of-magnitude gap between the UA field and the baseline Aether is the source
of the Casimir effect --- the residual pressure between two conducting plates measuring the
differential vacuum density between $\rho$vac,A and $\rho$vac,[SCm].

## §2 Vacuum Density in UQFF Field Equations

### 2.1 Ug2 (Outer Field Bubble)

$$U_{g2} = k_2 \cdot \frac{(\rho_{\text{vac},[UA]} + \rho_{\text{vac},[SCm]}) \cdot M_s}{r^2} \cdot S(r - R_b) \cdot (1 + \delta_{sw} \cdot v_{sw}) \cdot H_{SCm} \cdot E_{\text{react}}$$

Solution (Sun, r = Rb = 1.496$\times$1013 m, t=0):
$$U_{g2} = 1.2 \cdot \frac{(7.09 \times 10^{-36} + 7.09 \times 10^{-37}) \cdot 1.989 \times 10^{30}}{(1.496 \times 10^{13})^2} \cdot 1 \cdot 5001 \cdot 10^{46} \approx 1.18 \times 10^{53}\ \text{J/m}^3$$

The sum $\rho$vac,[UA] + $\rho$vac,[SCm] = 7.80$\times$10-36 J/m3 drives the outer field bubble energy density.

### 2.2 Ug4 (Star--Black Hole Interaction)

$$U_{g4} = k_4 \cdot \frac{\rho_{\text{vac},[SCm]} \cdot M_{bh}}{d_g} \cdot e^{-\alpha t} \cdot \cos(\pi t_n) \cdot (1 + f_{\text{feedback}})$$

Solution (Sun, t=0, tn=0): Ug4 $\approx$ 2.50$\times$10-20 J/m3

[SCm] is the intermediary vacuum that carries the gravitational influence of the galactic
black hole (Mbh = 8.15$\times$1036 kg) to the individual star across dg = 2.55$\times$1020 m.

### 2.3 Buoyancy Modulation (Ub1)

$$U_{b1} = -\beta_i \cdot U_{g1} \cdot \Omega_g \cdot \frac{M_{bh}}{d_g} \cdot (1 + \epsilon_{sw} \cdot \rho_{\text{vac},sw}) \cdot U_{UA} \cdot \cos(\pi t_n)$$

The solar wind vacuum density $\rho$vac,sw = 8$\times$10-21 J/m3 modulates buoyancy via the factor
(1 + \epsilon_{\rm sw}$\cdot$$\rho$vac,sw) = 1 + 0.001$\cdot$8$\times$10-21 $\approx$ 1 (negligible 10-24 correction at t=0,
but becomes significant during solar maximum when $\rho$vac,sw spikes).

## §3 Schwarzschild Proton as Density Anchor

From Aether13_16:

$$\rho_{\text{proton-BH}} = \frac{M_p}{V_p} = \frac{1.67 \times 10^{-27}\ \text{kg}}{10^{-45}\ \text{m}^3} \approx 1.67 \times 10^{18}\ \text{J/m}^3$$

At the Schwarzschild proton threshold, removing 10-39% of a proton's energy creates a
black hole --- confirming that the proton vacuum density 10-39 cm3 is the lower anchor
of the density series.

The Wheeler-DeWitt equation in UQFF:
$$\hat{H}_{\text{UQFF}} |\Psi\rangle = 0 \quad \Rightarrow \quad E_{\text{vac}} = \rho_{\text{vac},A} \cdot V_{\text{observable}} \approx 10^{-23} \cdot V_{\text{obs}}\ \text{J}$$

---

## §4 Casimir-UQFF Connection

The Casimir effect energy per unit area between plates separated by distance d:

$$\frac{E_{\text{Casimir}}}{A} = -\frac{\pi^2 \hbar c}{720 d^3}$$

In UQFF, this maps to the differential vacuum pressure between Aether layers:

$$\Delta \rho_{\text{vac}} = \rho_{\text{vac},[UA]} - \rho_{\text{vac},[SCm]} = 7.09 \times 10^{-36} - 7.09 \times 10^{-37} = 6.38 \times 10^{-36}\ \text{J/m}^3$$

This differential is the source of the Casimir attractive force: two conducting plates
locally suppress [SCm] permeability, increasing $\rho$vac,[SCm]/$\rho$vac,[UA] ratio above 0.1,
which drives plates together via the Ub1 buoyancy gradient.

### 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 $\delta = \beta_i \cdot S_{26}^{(3)} \cdot (\omega_{\text{SCm}}/\omega_{\text{bulge}})$.



## §A. Cosmogenesis-Linked Lagrangian (PAPER_877 Symbolic Export)

### §A.1 Sector Classification

This paper maps to **NS-compact** sector of the 9-sector UQFF Lagrangian (see
`uqff_lagrangian_derivation.py`).

### §A.2 Lagrangian Density

The sector Lagrangian density, linked to the PAPER_877 cosmogenesis master via the three reactive
quantum fundamentals (DPM, UA, SCm):

$$\mathcal{L}_{\mathrm{sector}} = \frac{1}{2}(\partial_mu \phi_{\mathrm{NS}})(\partial^\mu \phi_{\mathrm{NS}}) - V(\phi_{\mathrm{NS}}) + \mathcal{L}_{\mathrm{cosmo}}$$

where $\mathcal{L}_{\mathrm{cosmo}} = \rho_{\mathrm{vac,[SCm]}} \cdot f_{\mathrm{SCm}} \cdot (1 - e^{-\gamma t})$ inherits the ACP 6-stage evolution (PAPER_877 §2) and:

$$V(\phi_{\mathrm{NS}}) = \frac{1}{2} m^2 \phi_{\mathrm{NS}}^2 + \frac{\lambda}{4!} \phi_{\mathrm{NS}}^4 + \kappa \cdot \rho_{\mathrm{vac,[SCm]}} \cdot \phi_{\mathrm{NS}}$$

### §A.3 Euler-Lagrange Equation of Motion

$$\boxed{\frac{\delta S}{\delta \phi_{\mathrm{NS}}} = \nabla^2 \phi_{\mathrm{NS}} - (4\pi G \rho_{\mathrm{NS}}/c^2)\phi_{\mathrm{NS}} + \Omega_{\mathrm{spin}} \partial_t \phi_{\mathrm{NS}} = 0}$$

### §A.4 Cosmogenesis Linkage Chain

$$\text{PAPER\_877 Axioms} \xrightarrow{\text{DPM + ACP}} \rho_{\mathrm{vac}} = \rho_{\mathrm{UA}} + \rho_{\mathrm{SCm}} \xrightarrow{\text{Stage 5}} U_{b,\mathrm{seed}} \xrightarrow{\text{4 forces}} F_U_Bi_i \xrightarrow{\text{sector E-L}} \delta S/\delta \phi_{\mathrm{NS}} = 0$$

The chain traces from the three fundamental axioms (DPM proportion pair, ACP evolution, four U_g
forces) through vacuum density initialization to the sector-specific equation of motion. Every term
in the E-L equation inherits its physical origin from the cosmogenesis master.

## §B. VDS/DVP/BSH Deep Synthesis

### §B.1 Vacuum Density Series (VDS)

The canonical VDS ratio $\rho_{\mathrm{vac,[SCm]}} / \rho_{\mathrm{UA}} = 1.894$ governs the double-exponential vacuum condensate profile:

$$\rho_{\mathrm{vac}}(r) = \rho_{\mathrm{vac,[SCm]}} \cdot \exp\!\left(-\exp\!\left(-\frac{r - r_0}{\lambda_{\mathrm{VDS}}}\right)\right)$$

For this system, the local VDS sub-ratio is $0.051$ (near-threshold regime), placing it in the $t \to \pi$ collapse zone where the double-exponential transitions sharply from condensed to dilute vacuum. This threshold behavior connects to the PAPER_877 cosmogenesis Stage 1 vacuum density initialization: $\rho_{\mathrm{vac}} = \rho_{\mathrm{UA}} + \rho_{\mathrm{SCm}} = 7.799 \times 10^{-36}$ kg/m3.

### §B.2 Dipole Vortex Primes (DVP)

The DVP encoding maps the system's characteristic parameter onto the prime lattice:

$$p_{\mathrm{DVP}} = 61, \quad n_{\mathrm{channel}} = 24/26$$

Since $p_{\mathrm{DVP}} = 61$ is **resonant** (threshold at $p > 26$), the system's vacuum topology inherits resonant enhancement from the DVP lattice, amplifying UQFF coupling at specific radii where compressed matter achieves prime-indexed configurations. The DVP framework traces to PAPER_877 proto-nuclear shell formation: the DPM proportion pair $(f_{\mathrm{UA}}' + f_{\mathrm{SCm}} = 1)$ constrains which primes are accessible at each atomic number.

### §B.3 Buoyancy Saturation Harmonics (BSH)

The BSH saturation timescale for this sector is **104 yr** (spin-down equilibrium):

$$\mathcal{F}_{\mathrm{BSH}} = \sum_{j=1}^{26} \frac{1}{j} \cdot f_U_b \cdot \left(1 - e^{-[SSq] \cdot m/M_\odot}\right) \cdot \cos\!\left(\frac{2\pi j}{26}\right)$$

The $\tanh$ saturation envelope prevents unphysical divergence:

$$\mathcal{F}_{\mathrm{BSH,sat}} = \mathcal{F}_{\mathrm{BSH}} \cdot \left(1 - \tanh\!\left(\frac{t - t_{\mathrm{sat}}}{\tau_{\mathrm{BSH}}}\right)\right)$$

connecting to the PAPER_877 Stage 5 buoyancy seed $U_{b,\mathrm{seed}} = 0.1 \cdot (\hbar c/r^2) \cdot f_{\mathrm{SCm}}$ which initializes the harmonic series at cosmogenesis.
