It is sometimes the case that a comment is as delightful and enlightening as a post...this one does that. It raises and answers questions--may I say, almost irreverently....which I know @lemouth welcomes. He leads us down a dark, uncertain path and makes no promises. We follow, learn and question.

I don't have mathematical references or even a superficial understanding of physics (beyond which I am acquiring through these blogs), but I kept thinking as I read your comment of a book by Miguel de Unamuno: "La Niebla". Poor confused Augusto, the main character--cannot call him a protagonist because he learns he is just a character in a book. He doesn't write the script of his life--it is written for him.
Anyway, the intersection of physics and our perception of reality--that's where your comment took me. A very interesting journey. I won't go on, because my mind continues to make associations that go back to your comment, and @lemouth's journey into the primordial and the dark....nothing wimpy about that.
