DGTM in Astrobiology

Abstract

This working paper introduces DGTM in Astrobiology, a methodological extension of the Dynamic Gravitational Time Matrix (DGTM) for comparative evolutionary and habitability timeline analysis. The framework introduces the DGTM Earth-Time Multiplier, a reproducible factor relating accumulated local proper time along a defined astrobiological target worldline to accumulated proper time along a defined Earth reference worldline. Its purpose is to provide a transparent physical time-basis layer for comparisons involving planets, moons, exoplanets, spacecraft habitats, and other astrobiological environments. The framework does not model biological evolution rates, abiogenesis probabilities, ecological processes, or habitability itself; it supplies a physical proper-time baseline that can be used by downstream astrobiological and biological models. The paper defines worldline and reference-frame requirements, precision levels, machine-readable metadata, uncertainty treatment, reproducibility requirements, falsification criteria, redundancy conditions, and practical-negligibility criteria.
