4.7 How Energy Gets Out: Pores, Axial Perforation, and Edgewise Band-Like Subcriticality

Home ／ Chapter 4: Black Holes

Energy does not cross an absolute no-go zone. It escapes because the critical band shifts locally. Whenever, within a small patch, the minimum outward speed drops below the local propagation limit, the outer critical boundary temporarily yields in that patch. All outward transport still obeys the local speed ceiling; nothing outruns it.

I. Why the Critical Band “Grows Pores” and “Opens Grooves”: The Inevitable Outcome of Dynamic Criticality and Roughness

The near-horizon is not a smooth mathematical surface. It is a finite-thickness tensile skin that is continually rewritten by three ongoing processes:

• Fiber-sea drawdown and replenishment reconfigure the local material, effectively raising or lowering the propagation ceiling.
• Shear, reconnection, and cascades reorder the smoothest outward paths, effectively lowering or raising the minimum outward requirement.
• Core pulses and external disturbances inject energy and momentum into the transition zone, pushing certain patches into a more “yield-prone” state.

As a result, the outer critical boundary shows fine spatiotemporal corrugations. When a small patch experiences a brief crossover—slightly higher allowance and slightly lower requirement—a pore lights up. If such pores repeatedly appear along a direction and become connected, they form a through-going perforation or a band-like region of reduced criticality.

II. How the Three Escape Routes Operate

1. Ephemeral Pores: Local, Short-Lived, and Soft but Steady Slow Leaks

Origin

• Closure: The leaked flux reduces local tension or alters shear. As geometry resets, the curves separate and the pore closes naturally.
• Gating: The brief crossover of the two curves makes the outer critical boundary yield within a tiny patch.
• Trigger: A core stress pulse or an incoming wave packet is absorbed in the transition zone, raising local tension and fine-tuning geometry. The allowance curve nudges upward while the requirement curve dips.

Characteristics

• Feedback: Outflow weakens its own trigger, creating self-limitation—hence a “slow leak.”
• Flow type: Predominantly soft, broad flux. Intensity is modest yet stable, with little tendency for self-excited oscillation.
• Scale and lifetime: Small aperture and short duration; windows appear from micro-scales up to sub-ring scales.

When to expect

• Geometries with elevated core noise but lacking persistent directional bias.
• Objects with a thicker, more compliant transition zone, or during periods of frequent but low-amplitude external disturbances.

Observational signatures

• Multi-messenger: No expectation of correlated neutrinos or ultra-high-energy cosmic rays.
• Spectrum and dynamics: Enhanced soft/thick components; infrared and sub-millimeter, plus soft X-ray, grow more visible. There is little evidence of fresh jet knots, ejections, or notable acceleration.
• Time domain: After de-dispersion across bands, small common steps appear, followed by a weak, slow echo-like envelope—more like a “raised baseline.”
• Polarization: Slightly reduced fractional polarization in the lit patch; position angle continues a smooth twist; sharp flips are rare.
• Image plane: Local or global mild brightening of the main ring, slight thickening at the brightened azimuth, and occasional sharpening of faint inner sub-rings.

Consistency note

• Quantum tunneling: Black-hole pores and quantum tunneling reflect the same underlying logic (see Section 6.6).

2. Axial Perforation: Hard, Straight Transport Along the Spin Axis

Origin

• Waveguiding: The channel guides axial disturbances and suppresses lateral scattering, effectively raising the axial allowance and further lowering the requirement.
• Connectivity: Axially adjacent pores that flash repeatedly connect more easily, creating a slender, continuous low-impedance channel.
• Preset bias: Spin organizes near-core tension and shear into an axial texture. Along the axis, the “requirement” persists below other directions.

Characteristics

• Bottleneck: The narrowest throat sets the flux ceiling. A choke point caps the overall power.
• Threshold: Once formed, the channel self-maintains. It rarely quenches unless supply wanes or strong shear tears it apart.
• Flow type: High fraction of hard components; straight transport with strong collimation; the load can be sustained.

When to expect

• Greater persistence when the supply direction aligns with the axis.
• Systems with strong spin and long-lived axial ordering near the core.

Observational signatures

• Multi-messenger: Case-by-case statistical links to high-energy neutrinos; jet termini and hot spots are plausible accelerators of ultra-high-energy cosmic rays.
• Spectrum and dynamics: Non-thermal power law from radio to gamma rays, with a stronger high-energy end; observable knot motion, core shift, and acceleration or deceleration segments.
• Time domain: Fast, hard flares from minutes to days; cross-band signals are nearly synchronous, with high-energy bands leading slightly. Small quasi-periodic steps propagate outward with the knots.
• Polarization: High polarization; position angle remains piecewise stable along the jet; transverse Faraday-rotation gradients are common; near-core polarization correlates with the bright sector on the ring.
• Image plane: A straight, collimated jet; a brightened nuclear core; outward-moving knots that can appear superluminal. The counter-jet is weak or unseen.

3. Edgewise Band-Like Subcriticality: Tangential and Oblique Sprawl with Broad Reprocessing

Origin

• Energy redistribution: Energy migrates laterally and outward along bands. Repeated scattering and thermalization enable broad-area reprocessing.
• Band connectivity: When adjacent low-impedance stripes are laterally pulled into alignment, band-like corridors emerge along tangential or oblique directions.
• Shear alignment: The transition zone stretches scattered corrugations into stripes, forming a checkerboard of relatively low impedance between them.

Characteristics

• Plasticity: More responsive to external disturbances, which can imprint lasting geometric biases.
• Cadence: Longer paths and more scattering yield slower rise and long decay.
• Flow type: Intermediate speed, thick spectrum, wide coverage. Reprocessing and disk-wind–like flows dominate.

When to expect

• Post-burst periods in which stripes are stretched or spatial coherence increases.
• Objects with thick transition zones and long shear-alignment lengths.

Observational signatures

• Multi-messenger: Electromagnetic evidence dominates. On galactic scales, heated and evacuated gas marks feedback.
• Spectrum and dynamics: Reprocessing and reflection strengthen; X-ray reflection and iron lines become prominent; disk-wind blue-shifted absorption and ultra-fast outflows intensify; infrared and sub-millimeter emission from warm gas and hot dust increases, thickening the spectrum.
• Time domain: Slow rise and slow fade, from hours to months; inter-band lags depend on color; after strong events, band activity persists longer.
• Polarization: Moderate polarization; position angle varies in segments within bands; band-adjacent flips co-occur with edge brightening; multiple scatterings depolarize the signal.
• Image plane: Banded brightening at ring edges; wide-angle outflows and misty extensions across the disk plane—broader rather than needle-like; diffuse glow or halos near the core.

III. Who Sparks and Who Supplies: Triggers and Loads

1. Internal triggers
   • Shear pulses: Large-scale core surges push stress pulses into the transition zone, briefly raising the allowance.
   • Reconnection avalanches: Chains of micro-reconnections smooth geometry and depress the requirement.
   • Unstable-particle deconstruction: Short-lived tangles spray broadband wave packets, sustaining background noise and boosting ignition probability.
2. External triggers
   • Incoming wave packets: High-energy photons, cosmic rays, and external plasma are absorbed and scattered in the transition zone, locally tightening tension or smoothing paths.
   • Infalling clumps: Irregular clumps collide and transiently reorder shear and curvature, opening wider yield windows.
3. Load sharing
   • Core supply provides continuous base flow plus intermittent pulses.
   • External supply adds sudden boosts and geometric “polishing.”
   • The superposition sets which path is likeliest to light up now and how much flux it can carry.

IV. Revenue-Sharing Rules and Dynamic Switching

1. Allocation rule: The path with the lowest instantaneous “resistance”—conceived as the line integral of (requirement minus allowance) along the route—claims the largest share.
2. Negative feedback and saturation: Flux passage alters local tension and geometry, thus changing resistance. Pores self-close as they flow; perforations “fatten” until limited by the throat; band corridors heat up, grow thicker, and slow down.
3. Typical switches
   • Pore clusters → perforation: Frequent co-located pores along one orientation are pulled closer by shear, connect, and merge into a stable channel.
   • Perforation → bands: A torn axial throat or a supply pivot redirects flux into tangential and oblique spread, observed as broad reprocessing.
   • Bands → pore clusters: Bands break into islands, geometric continuity drops, and the flux returns to point-like slow leaks.
4. Memory and thresholds
   • Systems with long memory show hysteresis and phase-like “preferences.”
   • Thresholds depend on supply, shear, and spin. With slow environmental drift, allocations shift smoothly; with abrupt changes, allocations flip quickly.

V. Boundaries and Self-Consistency

• All outward transport arises from critical-band motion, not from crossing an absolute prohibition. The local tension sets the speed ceiling, and no path exceeds it.
• The three routes are not separate “devices” but different operating modes of the same skin under varied orientations and loads.

VI. One-Page Triage: How to Match What You See

• If the ring shows small co-window brightening, slightly lower polarization, a softer spectrum, and no jet knots: it is most likely ephemeral pores.
• If you see a collimated jet, hard fast variability, high polarization, moving knots, and possibly neutrinos: it is most likely axial perforation.
• If ring edges brighten in bands with wide-angle outflows, slow timescales, strong reflection and blue-shifted absorption, and a thick infrared spectrum: it is most likely edgewise band-like subcriticality.

VII. Summary

The outer critical boundary breathes, and the transition zone tunes. Drawdown and replenishment alter the material; shear and reconnection rewrite geometry; internal and external events provide ignition. Outward transport organizes into three common routes: point-like pores, axial perforation, and edgewise band-like subcriticality. Which route shines brighter, holds steadier, or lasts longer depends on which currently offers the least resistance—and on how the passing flux reshapes that route in return. This is a fully local, speed-capped gating mechanism and the actual way the near-horizon does work.
