Executive summary: The “quiet expansionist aliens” model proposes that advanced alien civilizations may expand across the universe without making visible changes, allowing life to emerge but preventing rival civilizations, which could explain the Fermi paradox and UFO sightings.
Key points:
Quiet expansionist model differs from “grabby aliens” by allowing life to emerge in colonized areas and not making visible changes.
Potential motives for quiet expansion include internal coordination, studying emerging civilizations, and avoiding detection.
Anthropic considerations favor quiet expansionist models over grabby ones, as they allow for more observers like us.
The model can potentially explain our apparent earliness in cosmic history and account for anomalous UFO sightings.
While not definitively true, the quiet expansionist model deserves more consideration as a plausible scenario for alien expansion.
Uncertainties remain about the likelihood and implications of this model compared to other possibilities.
