In a recent paper published in the International Journal of Astrobiology, a philosopher Dr. Vojin Rakić (voyin rack itch) reviews some 50 or so proposed solutions to Fermi’s paradox, including, that human life is so exceptional that it happened only once in the universe, that perhaps other civilizations destroy themselves like we are trying to do, civilizations broadcast radio and TV signals only for a relatively brief period of time, alien intelligent life maybe incomprehensible to our species, and that maybe the energy requirements and distances in the Milky way are too great allow us to discover others of our kind and many more ideas.
