The WR problem seems the same question as ... Why am I in that particular universe ? You are because that is consistent with you... As you can't feel all the other you who have not your luck you can't say that because you do not observe it, it is not like that after all... If tomorrow you observe a WR (a magical one ;) ) well... You'll know at least you're no more in a physical world devoid of white rabbits... and you can begin to be really scared ;) Also I think you will agree that all continuation where you're not... have a zero measure (from your POV). So you can't be where you can't be, nothing to be astonished here ;) Regards, Quentin > Thus, at each moment, the range of possible next observations is always > observed to be constrained precisely according to the quantum formalism. > Given that the only definition of the history of the observer is the record > of observations, I am greatly intrigued to know how one can, at each moment, > even in principle, derive the sensory specific next moment, according to > quantum rules, from this structure of information. > > > > > -- > You received this message because you are subscribed to the Google Groups > "Everything List" group. > To post to this group, send email to firstname.lastname@example.org. > To unsubscribe from this group, send email to > everything-list+unsubscr...@googlegroups.com<everything-list%2bunsubscr...@googlegroups.com> > . > For more options, visit this group at > http://groups.google.com/group/everything-list?hl=en. > > -- All those moments will be lost in time, like tears in rain. -- You received this message because you are subscribed to the Google Groups "Everything List" group.
