Fermi's Paradox and the Sociology of Extraterrestrials
Geschrieben von Claudius Gros   

The 1950 lunch-table remark by Enrico Fermi `Where is everybody' has started intensive scientific and philosophical discussions about what we call nowadays the `Fermi paradox': If there had been ever a single advanced civilization in the cosmological history of our galaxy, dedicated to expansion, it would have had plenty of time to colonize the entire galaxy via exponential growth. No evidence of present or past alien visits to earth are known to us, leading to the standard conclusion that no advanced expanding civilization has ever existed in the milky-way.

For the Fermi paradox to hold, alien societies need to be stable over millions of years, with a continuous drive to explore the universe and to expand. We have clearly no knowledge about possible sociologies of extraterrestrial societies. We cannot therefore not know, whether such types of societies might exist on other planets. But for what regards ourselves on earth, we can consider history for a clue.

When a society is stable for extended periods, like the old Egyptians, their drive for expansion and development is generally reduced. That is to say, that long-term sociological stability and the continuous drive for expansion seem to be mutually exclusive for human societies. If this conclusion is correct, it might have important consequence regarding the expansion of humanity in our milky-way. It might also harbor a possible solution for Fermi's paradox: There might be advanced and sociological stable extraterrestrial civilizations in our galaxy. But they wouldn't have come by to visit us, being sociologically stable over millions of years and having consequently lost their desire for expansion.
