All,

`Though we're not discussing entanglement per se, some of these examples`

`surely meet the criteria. So, my thought question for the day: is the`

`method of copying important?`

`Example #1: we start with a single marble, A. Then, we magically`

`create a copy, marble B--perfectly like marble B in every way. . .that is,`

`the atoms are configured similarly, the interaction environment is the`

`same--and they are indistinguishable from one another.`

`Example #2: we start with a single marble A. Then, instead of`

`magically creating a copy, we search the universe, Tegmarkian-style, and`

`locate a second marble, B that is perfectly equivalent to our original`

`marble A. All tests both magically avoid QM decoherence problems and show`

`that our newfound marble is, in fact, indistinguishable in every way from`

`our original.`

`Here's the question: Are the properties of the *relationship*`

`between Marbles A and B in Example #1 perfectly equivalent to those in`

`Example #2?`

`If the criteria involves simply analysis of configurations at a`

`precise point in time, it would seem the answer must be "yes." On the`

`other hand, if the method by which the marbles were created is crucial to`

`the present configuration, then the answer would be "no."`
