Cosmic Microwave Background as the Sole Possible Source of 1/f Baseline Noise in Biological Systems: An Impossibility Argument and Cross-Kingdom Verification (v1.1)

Abstract

v1.1 revision: all statements regarding the cosmological origin of the CMB (cosmic age/inflation/Big Bang) removed; only observational properties retained (2.725 K, 1/f spectrum beta=0.96, isotropy, persistence). The origin of the CMB has not been rigorously proven; no unproven external cosmological model is incorporated. ⚠️ 版本注记(2026-08-07):早期版本;后续发展见 CMB 底噪 v1.1 21741553/21741548。
