引力、熵与宇宙学：寻求清晰
Gravity, Entropy, and Cosmology: In Search of Clarity
摘要：
我讨论引力系统的统计力学，特别是它的宇宙学意义，并认为，在统计力学的基础上，许多关于这个问题的传统观点体现了重大的混乱，我试图提供一个更清晰和更准确的帐户。特别是，我观察到（i）引力\emph{in}熵计算的作用必须与熵\emph{of}引力区分开来，（ii）虽然引力坍缩是熵增加的，但这通常不是因为坍缩物质本身的熵增加，（iii）热力学第二定律的有效性并不归功于引力坍缩的统计力学。
英文摘要：
I discuss the statistical mechanics of gravitating systems and in particular its cosmological implications, and argue that many conventional views on this subject in the foundations of statistical mechanics embody significant confusion; I attempt to provide a clearer and more accurate account. In particular, I observe that (i) the role of gravity \emph{in} entropy calculations must be distinguished from the entropy \emph{of} gravity, that (ii) although gravitational collapse is entropy-increasing, this is not usually because the collapsing matter itself increases in entropy, and that (iii) the Second Law of Thermodynamics does not owe its validity to the statistical mechanics of gravitational collapse.
