How like a queen comes forth the lonely Moon.
George Croly, Diana
The last time I checked, astronomers had found 68 satellites orbiting the planets of the Solar System. it therefore seems absurd to suggest that our Moon is unique, much less that the Moon has anything to do with the Fermi paradox. Yet for decades there has been a nagging suspicion that what makes Earth special is the Moon.
To understand why the existence of the Moon might resolve the Fermi paradox, we need to answer three questions. First, in what way is the Moon unusual? Second, how probable is it that satellites similar to Earth's exist in other planetary systems? Third, in what way might the existence of the Moon have been necessary for the development of intelligent life?
