AG* *Yes certainly, Bobs clock is running only half as fast as Alice's clock, but that non-synchronization causes no logical contradictions if instantaneous communication is impossible. But if it is possible then that opens up a great big can of worms that as far as I can see can have only one solution. * * > I don't see how MW solves this problem. * *Just before a teenage William Shakespeare finds a copy of a book entitled "The Complete Works Of William Shakespeare" the multiverse branches, in one branch Shakespeare never finds the book and he composes all the plays and poems by himself, and in the other branch he just copies down what he sees in the book, and the information needed to do that came from another Shakespeare that lived in another world. * *> If their clocks aren't synchronized as Bob moves away from Alive, Bob > cannot conclude that Alice received his reply an hour before she sent the > question.* *Bob knows** Alice would send her question when the hands on her clock indicated two hours, but when Bob received the question and he sent his answer his clock only indicated one hour. Because both messages were instantaneous when Bob uses his telescope to look at the hands on Alice's clock they indicate one hour, and when he looks at her incoming message screen it says "the answer to your question how much is 11+3 is 14" which was one hour before Alice even thought of the question. * * John K Clark See what's on my new list at Extropolis <https://groups.google.com/g/extropolis>* wsd -- You received this message because you are subscribed to the Google Groups "Everything List" group.
