Kolmogorov Complexity, String Information, Panspermia and the Fermi Paradox
From the physics archive (though perhaps good luck figuring it out):
From: V. G. Gurzadyan Date (revised v2): Mon, 26 Sep 2005 16:46:55 GMT (4kb) Title: Kolmogorov Complexity, String Information, Panspermia and the Fermi Paradox Authors: V.G.Gurzadyan Categories: physics.gen-ph astro-ph Comments: Refs added. To appear in The Observatory Subj-class: General Physics; Astrophysics Bit strings rather than byte files can be a mode of transmission both for intelligent signals and for travels of extraterrestrial life. Kolmogorov complexity, i.e. the minimal length of a binary coded string completely defining a system, can then, due to its universality, become a key concept in the strategy of the search of extraterrestrials. Evaluating, for illustration, the Kolmogorov complexity of the human genome, one comes to an unexpected conclusion that a low complexity compressed string - analog of Noah's ark - will enable the recovery of the totality of terrestrial life. The recognition of bit strings of various complexity up to incompressible Martin-L\"{o}f random sequences, will require a different strategy for the analysis of the cosmic signals. The Fermi paradox "Where is Everybody?" can be viewed under in the light of such information panspermia, i.e. a Universe full of traveling life streams.
