Okay, so the definitely dead cat model (and likewise the definitely alive cat model - one and the same) is out. This leaves the neither- ead model and the both-alive-and-dead model, and the strong probability that within the Standard (or any presently feasible nonstandard) Model and given both practical and theoretical measuring constraints, which one is correct may be Godelianly undecideable without involving us in Heisenbergian observerparticipant tainting. This reminds me of the argument whether God is hermaphroditic or asexual; what difference could it make to anything else, since we can't use differences in anything else to decide it? The absence (or presence) of the invisible is difficult to detect; the location of the omnipresent is difficult to isolate.
