ET Probes, Nodes, and Landbases: A Proposed Galactic Communications Architecture and Implied Search Strategies

TL;DR

This paper proposes a comprehensive galactic communication architecture integrating probes, nodes, and land bases, suggesting implications for Earth's surveillance, contact likelihood, and SETI strategies based on galactic-scale considerations.

Contribution

It introduces an overarching galactic communication framework combining multiple methods, offering new insights into ET contact likelihood and search strategies.

Findings

Earth has been thoroughly surveilled

Earth will be contacted in due course

SETI beyond 35-50 light-years is futile

Abstract

Land-based beacons, information laden probes sent into our solar system, and more distal communication nodes have each been proposed as the most likely means by which we might be contacted by ET. Each method, considered in isolation from ET's point of view, has limitations and flaws. An overarching galactic communication architecture that tethers together probes, nodes, and land bases is proposed to be a better overall solution. From this more efficient construct flows several conclusions: (a) Earth has been thoroughly surveilled, (b) Earth will be contacted in due course, (c) SETI beyond half the distance that Earth's EM has reached (~35-50 LY) is futile, and (d) the very quiescence of the galaxy paradoxically implies that that Drake's N = many, and that there is a system of galactic governance. Search strategies are proposed to detect the described probe-node-land base communications pathway.
