*Sure, I'll watch it. But I am still waiting for your reply to
my question, posed around 10 times, why, based on S's
equation, every thing that can happen, MUST HAPPEN. And please
don't offer your BS that you've answered it repeatedly. Such a
claim would be blatent lie. Finally, I know what you haven't
offered the answer. It's really simple. You don't want to
admit the Emperor has no clothes, as such an admission might
trigger a coronary when you realize you've been preaching a
lie these many years. AG *
*I watched it. I can't say I fully understand it or believe it.
I'll probably watch it again. I do know that lately I am less
impressed with the cat experiment, as I recall a recent comment by
Brent; that there's no operator which has Alive and Dead as its
eigenvalues. This, IMO, means that the cat's wf isn't a valid
quantum wf. AG

You're misinterpreting what I wrote. I meant that being alive is a
superposition of a bazillion of different wave functions so it is
impossible to formulate a measurement operator which will return just
one of two values that actually correspond to Alive and Dead. In other
words the exist a range of states that count as alive, some of which are
dying, and a range of states that would count at dead, but some of which
are recovering. It doesn't mean there is no WF of the cat. I means that
alive and dead are only well defined in the extreme cases because the
cat has many intermediate states which we can't account for in our
measurement operator.
*
*
*If the cat's wf isn't a valid wf in QM, which is now my belief, does
the same apply to Decayed and Undecayed? That is, what is the operator
which has Decayed and Undecayed as it eigenvalues? AG*
No, for a simple particle or atom the decayed and undecayed states are
well enough know that we can create measurement operators.
*
*
*Another question relates to the superposition which involves the
Environment. Carroll claims the observer is contained in this
superposition as part of the Environment without experience it's in
such a state. Is this the origin of the Many Worlds in the MWI? If so,
this seems independent of S's equation, and follows directly from the
quantum definition of the wf as a linear sum of eigenvalues. AG

Eigenvalues of what...of the Schroedinger equation (including a
measurement interaction).
