&gt; The real mystery, for me, is: Why was the initial state of our universe so completely non-chaotic?<p>Here&#x27;s a possibility: if you &quot;start&quot; at a random state, after enough exploration of the state space, there would be a local minima that was arbitrarily well-ordered. Both directions of time would then view that as the &quot;past&quot;, and the other direction as &quot;future&quot;.<p>These perceptions as to the arrow of time would last until a state equivalent to heat death is reached, at which point the &quot;arrow&quot; of time would flip around again.
