Is there? Even if the unpredicitability is
in-principle? What is the huge difference?

So what, in your view, bugged AE about probability in
QM? AG
I asked you first.
Brent
IIRC, you asked what was bugging ME, not AE. My guess is
that he thought acausality violated locality and/or realism.
For example, the Pilot Wave theory assumes each particle has
a definite position and momentum. It doesn't violate the HUP
because the HUP simply limits what we can measure. AG
I asked you "What is the huge difference?" Which you ignored
and just asked another question.
Brent
But the difference is obvious and implied. Whereas the resultant
probabilties attained might be indistinguishable, the underlying
realities are clearly distinct, say between Copenhagen and
deBroglie-Bohm (Pilot Wave theory). Since, at heart, you're an
instrumentalist, I assume the distinction for you is
meaningless. AG
You can invent arbitrarily many theories of "distinct underlying
realities" which are empirically indistinguishable...that's why
they are just interpretations. The only use I see for
interpretations with no empirical difference is they may suggest
better theories. I see no other reason to prefer one
interpretation over another. You might as well introduce fairies
into an interpretation or ask Deepak Chopra which one is really real.
Brent
So if someone, like Bohr, comes up with a lawless universe, that's
fine with you; or do you deny the lawlessness? AG
A lawless universe that is predictable per the Schroedinger equation??
What does that mean?
