Can anyone make sense of this? I haven't watched the whole thing (on my phone) but it seems simply wrong to me. Like the part about the disordered state being like encryption that could be reversed. The 2nd law is about the entropy of a closed system. How does one decrypt without producing more entropy?<p>Another thing in find fascinating is if the universe did run backwards in time, we would never know as our memories only form by a process that produces more heat than order.
