Does information entropy play a role in the expansion and acceleration
  of the Universe?
  We propose an interpretation of the expansion and acceleration of the
Universe from an information theoretic viewpoint. We obtain the time evolution
of the configuration entropy of the mass distribution in a static Universe and
show that the process of gravitational instability leads to a rapid dissipation
of configuration entropy during the growth of the density fluctuations making
such a Universe entropically unfavourable. We find that in an expanding
Universe, the configuration entropy rate is governed by the expansion rate of
the Universe and the growth rate of density fluctuations. The configuration
entropy rate becomes smaller but still remains negative in a matter dominated
Universe and eventually becomes zero at some future time in a $\Lambda$
dominated Universe. The configuration entropy may have a connection to the dark
energy and possibly plays a driving role in the current accelerating expansion
of the Universe leading the Universe to its maximum entropy configuration.
