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.

Transfer entropy in physical systems and the arrow of time

Physical Review E, 2016
Recent developments have cemented the realization that many concepts and quantities in thermodynamics and information theory are shared. In this paper, we consider a highly relevant quantity in information theory and complex systems, the transfer entropy, and explore its thermodynamic role by considering the implications of time reversal upon it.

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.

Boltzmann's Entropy and Time's Arrow

Physics Today, 1993
Given the success of Ludwig Boltzmann's statistical approach in explaining the observed irreversible behavior of macroscopic systems in a manner consistent with their reversible microscopic dynamics, it is quite surprising that there is still so much confusion about the problem of irreversibility.

Fractals, Entropy and the Arrow of Time

2016
Why can we not move backward in time? According to Relativity, time is just one more dimension like length, width and height where we can go as easily backward as forward. What makes time special? Newton’s laws are symmetric in time and so is even Schrodinger’s equation which controls the happenings at the quantum level.

Entropy, Information, and Complexity or Which Aims the Arrow of Time? Scientific Explanation

2021
In this article, we analyze the interrelationships among such notions as entropy, information, complexity, order and chaos and show using the theory of categories how to generalize the second law of thermodynamics as a law of increasing generalized entropy or a general law of complification.

The Arrow of Time, Entropy and the Expansion of the Universe

1976
Setting aside the guidance of consciousness, we discover a signpost for time in the physical world itself. The signpost is a rather peculiar one, and I would not venture to say that the discovery of the signpost amounts to the same thing as the discovery of an objective ‘going on of time’ in the universe.
