    Weirdly, the math at the quanta level works in both directions (time-wise).

    I guess something happens when you get a few atoms together that changes this.

    Maybe AbouBenAdam has some insight.

      It still can’t be rigorously proven that thermodynamics works - if you look at the statistical mechanics papers on it they basically assume something is random that is not to do it. TBF, the empirical evidence is convincing, and the assumptions they do make are small, even infinitely small.

      The second law probably relates to pseudorandomness and P=NP, in the end, but that’s a big unsolved problem.

      Isn’t that when people always start talking about entropy and how that gives us an arrow of time?

      And I think whether math “works” within an incomplete model isn’t really proof. I mean I can calculate a negative amount of people on the bus… But that alone doesn’t make it possible/real.
