noted in surrogate sticky https://www.physicsforums.com/showthread.php?p=682928#post682928 I printed this paper out and tried unsuccessfully for an hour or so to understand his argument. maybe someone else can elucidate. I am stumped. The paper is short, 5 pages, with few formulas. It goes over the argument he gave at the Dublin conference last year, about BH information loss (not). I was hoping when his paper on this came out that I would understand his reasoning better, but it didnt happen.
