It's funny that is essentially a repeat of the same discussion I was having with Bill S on the other thread. If you apply quantum theory you get a multiverse with locked times it is a prediction. You can't have a bit each way on the side and say I accept QM but I don't think the universes are locked they contain states and the states implies locked time under QM.
It is interesting he doesn't discuss anything about the other universes he tries to dodge the bullet so to speak.
I would also add that he does not discuss the big problem with the false vacuum state interpretation he has favoured. Quantum tunnelling to a true vacuum state would have already occured leading to quantum suicide because any event that changes the number of observers in the universe will have fatal consequences on the universe.
