Paradox

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.
