Passive CO₂ capture and mineralization on existing mineral building surfaces: A falsifiable framework for Low-Operational-Energy carbon removal

Active direct air capture requires dedicated air contact, sorbent regeneration, and associated operational energy. This study theoretically examines a complementary concept in which existing mineral building surfaces act as distributed passive air contactors. The proposed Passive...

Conditional Abiogenesis Problem Part IV - Physical Feasibility Envelope

Abiogenesis Feasibility Envelope A Physical Exclusion Framework for Candidate Prebiotic Environments Overview The Abiogenesis Feasibility Envelope is a physical-chemical screening framework for evaluating whether a proposed prebiotic environment can support the conditions require...

Bridging Boltzmann and Prigogine: A Dissipative Extension of Statistical Entropy

This working paper develops a theoretical bridge between Boltzmann’s statistical interpretation of entropy and Prigogine’s theory of dissipative structures. The aim is not to modify Boltzmann’s entropy relation, but to extend its conceptual reach toward open, non-equilibrium syst...

The Dissipative Order Extension of the Second Law of Thermodynamics

Version Update: Working Paper — Condensed Publication Manuscript, July 2026 This update provides the condensed publication manuscript of The Dissipative Order Extension of the Second Law of Thermodynamics. The new version substantially consolidates and strengthens the framework d...

DGTM in Astrobiology

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...

The Conditional Abiogenesis Problem Part III

Description Part III of The Conditional Abiogenesis Problem examines whether the conditions developed in Parts I and II remain physically coherent when traced from system-level viability down toward quantum dynamics, chemical kinetics, transport processes, and nonequilibrium ther...
