Technosignatures of Self-Replicating Probes in the Solar System: A Comprehensive Analysis
Introduction
This paper presents a rigorous examination of the plausibility, rationale, and detectability of technosignatures associated with self-replicating (von Neumann) probes within the solar system. The author situates the discussion within the broader context of SETI, emphasizing the shift from traditional radio-based searches to the identification of technosignatures, which are less dependent on assumptions about extraterrestrial motives and more amenable to Kardashev-type classification. The work synthesizes theoretical, astrophysical, geochemical, and engineering perspectives to propose concrete strategies for the detection of evidence of prior or extant extraterrestrial robotic activity, with a particular focus on the Moon and asteroids as prime search targets.
Rationale for Self-Replicating Probes and the Fermi Paradox
The paper articulates the strategic logic underpinning the deployment of self-replicating probes for galactic exploration, both from defensive (Dark Forest hypothesis) and exploratory (Intelligence Principle) standpoints. The author argues that such probes represent an efficient mechanism for systematic resource tracking and knowledge acquisition, and that their proliferation should, in principle, saturate the Galaxy if multiple ETIs exist. The analysis incorporates game-theoretic models (Prisoner's Dilemma, Berserker strategy) and population dynamics (r- vs. K-strategies, Lotka-Volterra models) to demonstrate the robustness of probe expansion and the limitations of colonization models based on population pressure. The persistence of the Fermi paradox is maintained, with the assertion that self-replicating probes, if feasible, render many proposed solutions moot.
Resource Requirements and Mission Profiles
A detailed geochemical and mineralogical survey is presented, establishing the universality of resource distributions (Bowen's reaction series, presolar dust, extrasolar planetesimal accretion) and the suitability of asteroids and moons for raw material extraction. The author provides explicit reaction pathways for the separation and processing of Fe-Ni-Co alloys, silicates, and volatiles, emphasizing the minimization of waste and the adoption of lean manufacturing principles. The analysis concludes that technosignatures resulting from asteroidal processing are likely to be indistinguishable from natural processes due to the constraints imposed by efficient self-replication and just-in-time manufacturing.
Lunar Industrial Ecology and Nuclear Technosignatures
The Moon is identified as the optimal base for manufacturing operations, given its partial gravity, resource complementarity, and tectonic stability. The author constructs a near-closed loop lunar industrial ecology, leveraging indigenous resources (anorthite, ilmenite, KREEP minerals) and recycling all reagents. The feasibility of constructing Magnox-type nuclear reactors from lunar materials is demonstrated, with explicit extraction and processing steps for U, Th, and rare earth elements. The paper posits that isotopic anomalies (e.g., 232Th/144Nd, 232Th/137Ba) in lunar regolith may serve as robust technosignatures of prior artificial nuclear activity, analogous to the Oklo natural reactor on Earth. The scaling analysis indicates that a population of 1.5 million self-replicating factory modules could be constructed in 6.5 years, yielding industrial throughput and energy consumption on par with terrestrial civilization.
Artefact Detection and Anomaly Analysis
The author reviews state-of-the-art anomaly detection methodologies, including unsupervised deep learning (VAE, GAN), fractal geometry analysis, and attention-based explainability, applied to high-resolution lunar imagery. The limitations of current search volumes and the potential for buried artefacts are discussed, with the suggestion that lunar subsurface deposits associated with M-type asteroidal impacts represent ideal locations for deliberate concealment of artefacts accessible only to technologically advanced species. The economic and evolutionary logic of gift-exchange is invoked, proposing that universal constructor technology may have been left as a future payment for resource utilization, contingent on the emergence of indigenous intelligence.
Implications for AI, Ethics, and Future Developments
The paper addresses the intersection of self-replication technology and AI, noting that current LLM-based paradigms are insufficient for embedded sensorimotor interaction required for autonomous probe operation. The author advocates for hybrid symbolic-neural architectures with robust symbol grounding, constrained by ethical considerations to prevent harm. The potential for ASI to act as a Great Filter is discussed, underscoring the urgency of human space industrialization and the exponential leverage afforded by self-replication. The work speculates on the future trajectory of lunar industrialization, interstellar migration, and the resolution of the Fermi paradox through the discovery of technosignatures as a byproduct of human expansion.
Conclusion
This paper provides a comprehensive framework for the identification and interpretation of technosignatures associated with self-replicating probes in the solar system. The analysis integrates astrophysical, geochemical, engineering, and AI perspectives to propose targeted search strategies, robust detection methodologies, and plausible artefact locations. The implications for SETI, planetary science, and space industrialization are profound, suggesting that the resolution of the Fermi paradox may be achieved through the systematic exploration and industrialization of lunar and asteroidal resources. The work highlights the necessity of interdisciplinary approaches and the potential for future discoveries to reshape our understanding of extraterrestrial intelligence and technological evolution.
