Why do you and Clark persist in this error? Collapse, if it occurs,
does NOT depend on human consciousness.
OK but what you said made it depending of consciousness. There is
no collapse possible with the SWE, so what is the collapse? All
theories introducing a collapse in between the consciousness of the
observer and the observed objects seem highly speculative to me.
Measurement is just a specific instance of decoherence. There have
been "effective measurements" for billions of years.
OK. But not just in the universal wave, also in arithmetic, and
Mechanism forces them to be equivalent at some level, in a
verifiable way/
What is proved is that in all theories rich enough to add and
multiplied distinguishable inductive termes, like numbers, or
combinators, universal numbers and universal combinators exists, and
we have to retrieved physics from arithmetic using the self-
referential abilities of the universal machines (the Löbian chatty
one).
I would agree to the extent these objects connect with
Grothendieck's categories or Motivic. Quantum mechanics and
spacetime physics share properties of "magma" that is a category type.
You might elaborate on this. The point is that whatever the physical
reality is, it has to be the unique one in the head of all universal
machines/numbers, so if it shares properties of "magma" (whatever that
is), we can and should verify it in arithmetic. Then the G/G*
separation might separate the justifiable and non justifiable part of
the magma involved.
Chert or flint carry cosmic ray tracks, which indicate particles
(likely muons) had their wave functions reduced with the interaction
of the rock material many millions of years ago.
Not at all. When *we* do a measurement w just localized ourselves in
the universal wave/matrix (it works in all pictures). The wave never
collapse. I like feynman when he describe the collapse as a
collective hallucination. It is exactly what Mechanism ensures.
I tend to think the geologist looking at cosmic ray tracks in chert
is performing a classical measurement, at least on the level of FAPP.
What is a classical measurement? You do seem to believe in the
collapse (and in a irreducibly physical ontology). Ah, maybe you don't
as I see well below.
The quantum phase of superposition or entanglement associated with
the state reduction of particles interacting with the stone are long
gone.
Then the SWE, Dirac, Feynman does not apply to the classical realm,
but what is that realm, and how to test its existence? With the SWE
the quantum superpositions never disappear.
They have gone the way of T-rex or what ever other creatures lived
then. The phase still exists, for if we think unitarity if
fundamental then overlap phases and entanglement phases are
conserved, but in this case the overlap phases has long ago done the
"Elvis has left the building." What ever quantum phases there are
associated with the track are from more recent interactions.
OK. Thanks for reassuring me! But when searching the truth, we must
admit the existence of things which we cannot directly observe (like
quarks), and if you agree on the global unitarity, then, well, you get
the "parallel histories", even if we cannot interact with them. To
know the exact 10^120 decimals of the position of a coin (assuming
that makes sense) might need the terms in the universal wave which
involve the dinosaurs in the parallel histories, even for a Bohmian
(which will just not allow the dinosaurs wave to have particles).

I have a hard time thinking that a geologist looking at this has
performed a quantum measurement that reduces the wave function then
and there. It does not do much to invoke life either, for I doubt
that an unusually smart trilobite or cockroach in the Paleozoic
epoch would perform a measurement with some conscious idea of QM.
