Summary

  • In 1950 Italian physicist Enrico Fermi posed the question: If there are alien civilizations in our galaxy, why haven’t they communicated with or visited Earth?
  • This so-called Fermi’s paradox has inspired many possible answers, including the suggestion that intelligence is unlikely and therefore rare in the universe.
  • But a new “law of nature” says there is an inevitable increase in complexity over time.
  • This should mean advanced, complex life is very likely, and the rarity of intelligent life in the universe is simply a reflection of how unusual and recent human evolution is.
  • The idea is that biological evolution is a special case of a more general process of greater complexity increasing over time.
  • This process forms its own future and creates new possibilities for the universe, meaning the development of life and intelligence is somewhat inevitable.
  • The work is controversial and whether the idea can be properly tested remains to be seen.
