Test: Employ future CMB missions (e.g., LiteBIRD, PICO) to search for anomalous symmetries and subharmonic structures in the CMB angular power spectrum.
3. Cosmic Web Spectral Analysis
Hypothesis: The filament and void structure of the LSS should conform to predicted modal patterns, especially nested shells and standing wave nodes.
-
Test: Perform Fourier transform or wavelet decomposition on LSS data (e.g., from Euclid, DESI) to extract dominant spatial frequencies and compare with theoretical eigenmode spectra.
8.4 A New Class of Cosmological Probes
To further explore Resonant Genesis, we advocate the development of a new class of cosmological observables and instruments:
Resonance Spectrographs: Analogous to optical spectrometers, but designed to detect resonant density fluctuations and spacetime mode coupling signatures.
Multi-scale Modal Interferometry: Instruments optimized for detecting nested resonance patterns across cosmic scales---from baryonic acoustic oscillations to megastructure alignments.
Fractal-Curvature Mappers: Tools to scan for non-Euclidean self-similar structures embedded in cosmic data, based on fractal geometry and curvature flow techniques.
