Black Hole Missing Intermediate Sizes in the DRUMS Framework

1. Field Ontology

The DRUMS framework models spacetime as a coherent superfluid field:

\[ \Psi(\mathbf{x},t) = \sqrt{\rho(\mathbf{x},t)} e^{i\theta(\mathbf{x},t)} \]

Velocity arises from phase gradients:

\[ \mathbf{v} = \frac{\hbar}{m} \nabla \theta \]

2. Black Holes as Quantized Topological Defects

Black holes correspond to quantized vortices with circulation:

\[ \Gamma = \oint \mathbf{v} \cdot d\mathbf{l} = n \frac{h}{m} \]

This enforces discrete angular momentum states:

\[ L \sim n \hbar \]

3. Energy–Size Scaling

The energy of a vortex structure scales as:

\[ E(R) \sim \rho \int (\nabla \theta)^2 dV \]

For a vortex of radius \(R\):

\[ E(R) \sim \rho \frac{n^2}{R^2} \cdot R^3 = \rho n^2 R \]

This gives a linear scaling:

\[ E \propto n^2 R \]

4. Stability Condition

Stability requires balance between kinetic and quantum pressure:

\[ Q = -\frac{\hbar^2}{2m} \frac{\nabla^2 \sqrt{\rho}}{\sqrt{\rho}} \]

Equilibrium occurs when:

\[ \frac{n^2}{R^3} \sim \frac{\hbar^2}{m R^3} \]

Which implies discrete stable radii:

\[ R_n \sim n \ell_0 \]

where \(\ell_0\) is a characteristic coherence length.

5. Instability of Intermediate Scales

Intermediate sizes require non-integer or unstable configurations:

\[ R \neq n \ell_0 \Rightarrow \text{no stable phase winding} \]

Such configurations experience energy gradients:

\[ \frac{dE}{dR} \neq 0 \]

Driving rapid evolution toward nearest stable state.

6. Bifurcation Behavior

Unstable intermediate structures bifurcate via:

This is governed by energy minimization:

\[ \Delta E \sim \rho (n+1)^2 R_{n+1} - \rho n^2 R_n \]

7. Observational Gap Emergence

Because only discrete radii are stable:

\[ R \in \{R_1, R_2, R_3, ...\} \]

There exists a natural absence of intermediate sizes.

Transitions occur rapidly compared to observational timescales:

\[ \tau_{transition} \ll \tau_{cosmic} \]

8. Mass Scaling

Mass relates to radius via density integration:

\[ M \sim \rho R^3 \]

Thus discrete radii imply discrete mass bands:

\[ M_n \sim \rho (n \ell_0)^3 \]

9. Final Interpretation

The absence of intermediate-mass black holes arises naturally in DRUMS due to:

Thus, the observed mass gap is not anomalous but a direct consequence of the underlying superfluid structure.
