Def Disorder/Feynman: the number of ways in which elements (molecules) can be arranged inside so that it looks the same from the outside.
Def Order/Feynman: the fact that the number of possibilities to arrange elements so that the structure looks the same from the outside is limited.
Disorder/Feynman: if all laws of physics are reversible, whence the irreversibility? How is it that our everyday situations are always out of balance?

How does disorder evolve out of order?
We do not yet know the origin of order.
E.g. container with mixed white and black balls.

It would be very unlikely, but not excluded, that after a time the colors separate again. As time progresses, they are mixed again afterwards.
So it is a possible explanation that today's order of the universe is simply a question of luck.

This type of theory is not asymmetrical, because we can ask how the state looks either a bit into the future or to the past.
In any case, we see a gray spot at the interface(?), because the molecules mix again. (I.e. in both directions).
E.g. variant: we only look at one part of the container at once. Question: What should be derived from that for the regions that have not been seen?
We have to assume the most likely case, and that is certainly not that the other molecules are also ordered.
If our order stems from a fluctuation, we would not expect order to prevail in other places.
Feynman: Thesis the universe was ordered in the past. This theory predicts that there is order in other places too, and that is what we observe (stars, galaxies).
Our present order comes from a higher order at the beginning of time.
Today's order is a reminder of an earlier order.
Therefore, we have memories of the past and not the future.

Knarre: works only, because it is part of the universe. If isolated for a long time, it would no longer be more likely to turn in one direction than the other.
The asymmetrical behavior is connected with the asymmetry of the entire universe.
