In fact, I DO think it's a mental
illness. AG
It's not just wrong, but a gross
dysfunction of judgment. Joe the Plumber
goes into a lab or his closet, shoots a
single electron at a slit, and by so doing
creates uncountable universes, all with
copies of himself, replete with his
memories. Sure. AG
You may as well protest on the same basis that
the universe can’t be so wastefully large.
I don't see how that follows. Unfortunately, one
cannot PROVE that the many worlds allegedly implied
by the MWI interpretation don't exist, which is why
I insist the True Believers are judgment impaired.
Do you really believe that trivial actions by mere
humans, accidents of evolution, can create entire
universes? AG.
No, because that's not what happens, at every
interactions, universes split/differentiate... Humans
or not.
I think that's a misleading way to look at it. First,
the vector in Hilbert space representing the state of
the universe just rotates around. It never "splits".
What we refer to as "splitting" is the projection onto a
plane in the Hilbert space that corresponds to a certain
"classical" world. Second, this "classical" world plane
is not sharply defined. Almost all interactions do not
make any difference to it, i.e. they only make Planck
sized changes to the action and correspondingly tiny
tilts to the projective plane. The myriad atomic
interactions in your body don't make any classical
difference.
Yet if QM is the theory of reality, there is no classical
world that exists ontologicaly... So makes no difference to
who, what?
That the ontology of the world is quantum is a theory. The
theory is derived from and supported by evidence which is
stuff experienced by you and me. Our experience of the world
is "classical" (notice I used scare quotes, as I did above).
Bohr was right when he observed that science and knowledge
are only possible in a "classical" world; a world in which
records exist and observers can agree on them and we do not
observe macroscopic superpositions.
If QM is reality, microscopic change are parallel realities even
if your conscious state is compatible, span over them...Hence
computationalism.
*IF* QM is reality...or is it just our best current model of
reality. That's part of my point. Ontologies come from theories,
which come from epistemology.
Well I've said If... And also, unless you deny any ontology, if QM is
true, then these microscopic changes makes parralel realities... Then
you have to have a theory of mind which can explain that the same
conscious state can supervene on these different micro states.
Don't repeat your if....i've said it, and no epistemology doesn't
precede ontology, it does only in our discussion about it, but IF
there is something really real, it precedes everything.
Fine, but don't pontificate based on "if".
