Abstract:
e propose an interpretation of the expansion and acceleration of the Universe from an infor mation theoretic perspective. 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 -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.
