The ”Great Silence” of the Fermi Paradox is conventionally attributed to the scarcity of extraterrestrial intelligence (ETI) or the insurmountable barriers of spatial distance. This paper challenges these sociological and spatial assumptions by proposing a physical framework based on non-equilibrium thermodynamics and signal processing theory. It is posited that human perception is confined by ”Scale Geocentrism”, a bias presupposing that intelligence manifests exclusively within mesoscale timeframes and chemical energy levels. By establishing a positive correlation between environmental energy flux (ΦE) and the coupling frequency (fc) of biological consciousness, a spectrum of life is constructed, spanning from high-frequency entities dominated by nuclear forces to ultra-low-frequency structures dominated by gravitation. Applying the Shannon-Nyquist sampling theorem, it is demonstrated that signals from these ”ultra-fast” or ”ultraslow” civilizations are mathematically orthogonal to the human perception bandwidth (1,100 Hz). Consequently, these signals manifest as thermal noise or static physical background respectively. The paper concludes that the universe is not silent; rather, the detection bandwidth of current SETI methodologies is insufficiently tuned to demodulate the multi-scale cosmic symphony.
