I would think each observer splits the worlds in er own reference frame. Quite solipsistic, in a way, in the sense of there only being one real observer per world. This pushes the problem into how the disparate worlds come to interact - ie how does observer A compare notes with observer B. We can note that from observer A's perspective, observer B is a physical process (a human being, a brain, or even just some words displayed on a computer screen), and thus compatible with all other physical processes in A's world. Likewise for observer B. For space-like separated observers, from A's perspective, the physical process that is B is receipt of communication, more likely the words displayed on the computer screen in the examples above. This occurs at subluminal speed. The worlds splitting will be instantaneous in observer A's reference frame (ditto a completely independent split in observer B's reference frame). This does contrast with the point of view that MWI branching is more of a physical process that proceeds at subluminal speeds a la David Deutsch. But is there a problem with that picture? -- ---------------------------------------------------------------------------- Dr Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Senior Research Fellow [email protected] Economics, Kingston University http://www.hpcoders.com.au ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
