Alien AI Might Turn Advanced Civilizations 'Invisible' in a Cosmic Blink

Most stars have planets, with! over 6,000 exoplanets discovered so far, suggesting countless potentially habitable worlds in the Universe.

Despite searching for evidence of alien civilizations, none has been found. Theories include: life not existing elsewhere, Earth being in a "cosmic zoo", civilizations self-destructing, or humanity being the first.

These ideas are unprovable and unsatisfactory. A new paper re-examines Carl Sagan's musings, suggesting AI might be the reason for the lack of detection.

This idea adds to the existing theories, providing a new perspective on the mystery of missing alien civilizations.

Author's summary: Alien AI may make civilizations invisible.
