The Earth's Biosphere as a Conformal Receiver: Universal 1/f Signals from Greenhouse Gases to Active Galaxies

Key Points

• To explore the commonalities in spectral behavior between Earth's biosphere and active galactic nuclei.
• Analyzed residual time series of CO₂ and CH₄ alongside active galactic nuclei (NGC 4151) for spectral exponent calculation.
• Determined the spectral exponent β for each entity, finding a commonality around β≈1.
• CO₂ (β=1.136) and CH₄ (β=1.595) exhibit a similarity in spectral behavior with active galaxies (β=1.062).
• All examined systems fall into a common universality class defined by the Axiomatica Universalis.
