Hi Fabien,
Thank you for your great comments!
Your first question: if my paper is right, then a superposition exists when a fact does not exist, unrelated to knowledge. When an event occurs, then there is no longer a superposition. When I toss a coin but don't look at the result, there is still a fact about the result, a fact that is embedded in correlations with other facts about the universe. But that is different from the lack of a fact.
Not sure I get your second question. The 2nd law is not actually a "law" in the sense that classical processes are in principle reversible, so the increase in entropy appears as a statistical result. Whereas if there is a fact that "it rained yesterday" then this fact will be embedded in correlations with photons that speed outward to the night sky and can never, even in principle, be caught and "uncorrelated" to reverse the fact.
Third - THANK YOU!! I just downloaded the paper and am extremely excited to read it. One of my goals in writing and submitting this essay was precisely to see if anyone had done related research.
Thank you again for your notes and thoughts!
Andrew
