Beyond Anthropocentrism: A Relational Coherence Framework for the Drake Equation

As much as it is a critical backbone of astrobiology, Drake Equation has anthropocentric tendencies that have restricted its forecasting abilities. This paper re-casts it in terms of a scale-invariant physics on the basis of octonionic algebra Relational Coherence Theory (RCT) https://doi.org/10.5281/zenodo.16423366. Eradicating the biochemical assumptions in favour of universal coherence metrics (measuring life, consciousness and sustainability by information-theoretic thresholds) we solve the A-Index problem (anthropocentrism reduced to 0.14 vs. 0.71). The resulting RCT-Drake Equation and allows one to detect non-terrestrial intelligence even in cosmological terms.
