Entropy, inflation and the arrow of time

Classical and Quantum Gravity, 1991
One of the motivations for the introduction of inflation was to explain the large entropy of the observed Universe. Penrose has recently pointed out that the entropy of the observable Universe is small when compared with the maximal possible entropy. The authors show that this phenomenon is also a natural consequence of inflation.

Entropy, Information, and the Arrow of Time

The Journal of Physical Chemistry B, 2010
We shall investigate the relationships between the thermodynamic entropy and information theory and the implications that can be drawn for the arrow of time. This demands a careful study of classical thermodynamics and a review of its fundamental concepts.
