We propose an interpretation of the expansion and acceleration of theUniverse from an information theoretic viewpoint. We obtain the time evolutionof the configuration entropy of the mass distribution in a static Universe andshow that the process of gravitational instability leads to a rapid dissipationof configuration entropy during the growth of the density fluctuations makingsuch a Universe entropically unfavourable. We find that in an expandingUniverse, the configuration entropy rate is governed by the expansion rate ofthe Universe and the growth rate of density fluctuations. The configurationentropy rate becomes smaller but still remains negative in a matter dominatedUniverse and eventually becomes zero at some future time in a $\Lambda$dominated Universe. The configuration entropy may have a connection to the darkenergy and possibly plays a driving role in the current accelerating expansionof the Universe leading the Universe to its maximum entropy configuration.

Does information entropy play a role in the expansion and acceleration of the Universe?
