Searching for Extraterrestrial Intelligence by Locating Potential ET Communication Networks in Space
Ross Davis

TL;DR
This paper proposes a network analysis approach to identify promising regions in space for detecting extraterrestrial technosignatures, focusing on habitable exoplanets and their clusters to improve SETI search efficiency.
Contribution
It introduces a novel network topology model of exoplanets and hypotheses to guide SETI efforts toward more probable locations of ET communication networks.
Findings
Network analysis highlights potential ET communication hotspots.
High concentration of habitable planets increases likelihood of technosignatures.
Clusters of habitable systems are promising targets for SETI searches.
Abstract
There have been periodic efforts in recent decades to search for extraterrestrial intelligence (SETI), especially by trying to find an extraterrestrial (ET) radio signal or other technosignature in space. Yet, no such technosignatures have been found. Considering the vastness of space, finding such technosignatures has been described as trying to find a needle in a cosmic haystack. To help resolve this, two hypotheses are proposed to aid SETI researchers in narrowing the search for ET technosignatures, based on a network analysis approach to locate where in space potential ET communication networks would most likely be. A potential ET communication network can use exoplanets as communication access points (e.g., placing a communication satellite into planetary orbit, or an antenna on a planetary surface). The approach uses a topology where exoplanets are represented as nodes, and the…
