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.
