A new paper proposes the 'quiet expansion filter,' suggesting that old, stable civilizations that achieve autonomous AI-cosmoindustry have likely not arisen in the part of the Galaxy capable of reaching the Solar System.

Why
The paper attempts to resolve the Fermi paradox by suggesting that interstellar expansion, after a certain technological threshold, would be machine-mediated, distributed, low-noise, and partly biological rather than overtly noticeable.

How this affects you

This hypothesis posits that advanced alien civilizations, if they exist and have achieved AI-driven self-replicating space industries, would expand in a way that is quiet and difficult to detect, potentially explaining why humanity has not yet observed them. This could shift scientists' focus toward searching for subtle artifacts or anomalies rather than large-scale energy signatures.
