"Existentially speaking, is there such a thing as half a piece of cake?" -- kayre

This evening at dinner the fundamental dynamics of lightsabres came up. Specifically, how does the color encoding work? Is Luke's blue because Luke prefers blue, or because any lightsabre Luke uses will channel Luke-specific force, which is blue? If so, do the admission criteria at Jedi University include "sabre does not glow red" (and if not, why not)? Are there important qualitative difference between blue and green sabres, both of which appear to channel the light side of the force? Surely these are important research topics for someone out there who has, you know, seen all the movies.

If the other half is still attached, doesn't it make it all one thing? I was under the impression that for the purposes of referential sanity, most people didn't allow the division of connected consistent solid objects up into an arbitrary number of virtual "things".
If you want to refer to the halves separately, it would seem that one half would need to be in a different context than the other, like if it were on the other side of a dimensional rift, or covered with a handkerchief and invisible, or something. That would provide a situation where it would be natural to refer to one half independently of the other, so it would consist as the entirety of one thing.
