Overview

In 1970, Stephen Hawking introduced the model of black hole entropy, and hence black hole thermodynamics.

In 1939, Subrahmanyan Chandrasekhar, in his book*An Introduction to the Study of Stellar Structure*, devoted his the first chapter, on __astrophysical thermodynamics__, to laying out a thermodynamic foundation for the study of stellar structure using the thermodynamics of Greek mathematician Constantin Caratheodory (1908), in particular the so-called Caratheodory theorem.

In 2001, Eric Chaisson, his*Cosmic Evolution: the Rise of Complexity in Nature*, outlined a “lightly quantitative, thermodynamics-oriented treatment” of radiation, matter, and ‘life’ (powered CHNOPS+ things), using what he calls “energy flow-rate density” (ΡΊ), in units of ergs per second per gram, as a complexity measure for phenomena of all kinds and scales.

The general nature of the thermodynamic operation of the universe, however, is relatively unknown, depending on phenomenon such as dark energy, boson-fermion relationships, the open or closed thermodynamic system possibilities of the universe, the puzzling rate of expansion of the universe, a lack of a unified theory of the fundamental forces or interactions, e.g. electromagnetic vs. gravity, the nature of black holes and entropy, etc. The central question in human thermodynamics is how does the thermodynamic operation of the universe relate, interact, or connect to the thermodynamic operation of human life, if at all?
