Re: [math-fun] Mathematics of SETI protocols ?

:) I didn’t mean to start a debate about the existence of aliens or not or Fermi’s Paradox, really just to point out that the content/math of any message/s would need to be modified based on the method/s of communication. Having said that, as to the definition of “intelligent” creature, I’d say one that could comprehend the meaning of “I think therefore I am” in whatever language - of course that’s if it’s translatable, it assumes a concept of self which may not actually be necessary for actual intelligence ? I guess an understanding of math beyond just +-*/ would do. With respect to types of alien, I don’t exclude anything really - including the intelligent nebula in Van Vogt’s “The Voyage of the Space Beagle”.
