  We attempt to describe geometry in terms of informational quantities for the
universe considered as a finite ensemble of correlated quantum particles. As
the main dynamical principle, we use the conservation of the sum of all kinds
of entropies: thermodynamic, quantum and informational. The fundamental
constant of speed is interpreted as the information velocity for the world
ensemble and also connected with the gravitational potential of the universe on
a particle. The two postulates, which are enough to derive the whole theory of
Special Relativity, are re-formulated as the principles of information entropy
universality and finiteness of information density.
