A new scientific framework suggests that even if signals or physical traces from alien civilizations reached Earth, detecting them requires deep research, AI-driven analysis, and long-term patience.

In an article I published on March 9, I did not merely call for “searching” for extraterrestrial civilizations. I argued for advancing the study of technosignatures as a comprehensive scientific field in its own right — and for systematically integrating artificial intelligence (AI), both as a research tool and as a practical means of detecting anomalies.

The approach I outlined moves from a passive mindset — waiting for a signal or a direct encounter — to an active one:

Understanding how technology leaves traces, and searching for them across multiple........
