Entropy and Relativity

  1. Sep 13, 2012 #1
    Since the entropy increase in a system is a function of time, it would seem that for different observers, rates of entropy would move differently. I am struggling a little hear with putting this into a coherent question, as I am a layman, but the jist is: both the notion of a closed system and the observation of time are dependent on an observer. What is the relationship between the thermodynamic arrow of time and the role of the observer in relativity? I imagine this is a complicated, so links to articles or such would be sufficient.

    Entropy is a function of time and can be used as a clock. It behaves like any other clock in relativity.
