You could model a block universe as a big stack of Life boards, where the time dimension is represented by the spatial displacement between the boards. There's no way the observers in such an arrangement can step out of one board onto another, backwards or out of sequence. Some would say that the stack of boards does not count as a computation, and others that even if it counts as a computation it doesn't count as a conscious computation; that to reach such states you need causality and for causality you need fundamentally real time, not block pseudo-time. I don't see any justification for such claims beyond a desire to preserve the magic in the world. -- Stathis Papaioannou --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Everything List" group.
