Book: “Why does the world exist?” page 61. By Jim Holt.
====..
Can it be assigned an entropy?
The computation is not hard.
If a system – anything from a cup of coffee to a possible world – can
exist in N different states, its maximum entropy equals log(N).
The Null World, being perfectly simple, has only a single state.
So its maximum entropy is log(1) = 0 – which also happens to equal
its minimum entropy!
So Nothingness, in addition to being the simplest, the least arbitrary,
and the most symmetrical of all possible realities, also has the nicest
entropy profile. Its maximum entropy equals its minimum entropy
equals zero. No wonder Leonardo da Vinci was moved to exclaim,
perhaps somewhat paradoxically: “Among the great things which
are found among us, the existence of Nothing is the greatest.”
===========…
How is possible to understand:
“Its maximum entropy equals its minimum entropy equals zero.”?

It's much easier to just use the Anthropic Principle: the world exists so that we are here to ask the question.

In my opinion the situation when “maximum entropy equals its
minimum entropy equals zero” is similar to the paradox of
Schrodinger’s cat that is simultaneously alive and dead.

Apparently your whole point in starting the thread was so that you could have a conversation with your alter ego. Not gonna fly.
