What if frequencies aren't properties of sound — they're permissions granted by geometry? A 4m room only allows wavelengths that fit its boundaries. The allowed set follows a dyadic ladder: 42.875 → 85.75 → 171.5 → 343 Hz Each step doubles. Each doubling halves the mode cell area. The room isn't a container for sound. It's a filter. Same math governs CMB power spectrum anomalies at cosmological scale. Boundary conditions all the way down. @physics
