Falsification of Quantum Cosmic Brain Stable-Channel Hypothesis: Post-Perihelion Observations of Interstellar Comet 3I/ATLAS

This work presents a preregistered falsification test of the Quantum Cosmic Brain (QCB) framework using volatile composition measurements from interstellar object 3I/ATLAS. A quantitative prediction was made prior to perihelion: CO₂/H₂O > 5 would support the hypothesis, while CO₂/H₂O < 2 would constitute strong falsification. Post-perihelion observations yielded CO₂/H₂O ≈ 0.13, decisively falsifying the tested hypothesis at astronomical unit scales. This paper documents the prediction, methodology, observational data, and implications of the negative result. The outcome constrains the applicability of QCB-type scalar couplings and demonstrates the framework’s falsifiability.
