    Is the cosmological arrow of time just a special case of the thermodynamic arrow of time, where the universe is the isolated system?

    short answer: yes

    the longer answer is nicely summed up in this post by Sean Carrol on the blog Cosmic Variance


    Its not an overly long read and helps to explain a lot of the issues surrounding the cosmological arrow of time and how our Universe could have started in such a low entropy state.
