Local Void-Shell Filtering: A Rotational Vacuum Dynamics Explanation for the Hubble Tension, JWST Early-Galaxy Observations, and Fermi Paradox

This technical note presents updated observational evidence from April 2026 Fermi-GBM subthreshold triggers that extend the multi-void instability reported in Franklin (2026b). Using the Cole Genesis Equation, we demonstrate that the stressed void-filament shell surrounding the Local Group functions as a frequency-dependent low-pass filter. 

Microwave (CMB) and infrared (JWST) signals experience significantly greater attenuation than visible or gamma-ray signals when crossing this shell. The resulting differential filtering simultaneously accounts for three major cosmological puzzles as measurement biases rather than new physics:

• The Hubble tension (CMB microwaves are more strongly suppressed than visible/near-IR Cepheid/supernova light)
• The JWST “impossibly mature” early galaxies (IR phase-shift and attenuation produce luminosity and age biases)
• The Fermi Paradox (the Local Group is radio-opaque while visible and high-energy windows remain relatively open)

We show that our cosmic location inside a dynamically active void shell introduces systematic, wavelength-dependent biases in cosmological observations, thereby resolving several long-standing “crises” without requiring new particles, modified gravity, or unknown dark-energy components.
