Answers: Why haven't we found evidence of alien civilizations yet?
- Drake equation
- Fermi paradox
- Great filter theory
- Extraterrestrial intelligence
- Coronal mass ejections
- Chelyabinsk meteor
What it concludes
- The Fermi Paradox highlights the contradiction between the high probability of extraterrestrial civilizations and the lack of observational evidence.
- The Great Filter theory suggests that complex barriers prevent civilizations from achieving space travel or long-term survival, explaining why we have not found alien life.
- Extreme cosmic events like solar storms and asteroid impacts pose severe threats to planetary civilizations and could act as filters.
- Earth may have already passed the Great Filter, making it one of the few surviving civilizations in the galaxy.
