I just checked a triablogue entry on possible worlds and I must say that my views are not resembling the possible worlds they picture there. For instance they talk of a Moses for each possible world and a Jesus for each possible world. I dont believe that. I believe that each universe has their own particular things. Some may not even have any matter in them because of different physical constants. And the other if they have things at all, they cant be humans, because humans are a thing of this universe only. If they have sentient beings that look very much like humans, they will still be the same humans with this universe, even if they call themselves "humans" there. And I dont believe that there is a replica of each of us in other universes.
This kind of view expressed in there is just making a replica of this world, like the other worlds are just off-shoots of this world. this is not what I believe. I believe in totally seperate universes, that have no connection to one another. Different spacetimes. And the things in them aren't the same things, for instance saying "in one of the possible worlds Jesus was resurrected" makes no sense to me. Because there is only one Jesus and he lived here.
