Demystifier's latest activity
-
Demystifier reacted to Sambuco's post in the thread Graduate Resolution of the Frauchiger-Renner paradox with
Informative.
Since I don't think anyone has mentioned it before, I'm sharing this paper where Del Rio and Renner respond to Polychronakos' work. Lucas. -
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Since RQM is inspired by relativity, let me use an analogy with black holes in general relativity. From the point of view of some...

Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.I agree it's hard, it takes some effort to see it this way. But they all have in common one crucial thing: There is never a collapse in...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.No. See my post #39 in which I explain how all interpretations say essentially the same, but in a different way.

Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Ok, now your point of view is clear, and it's a perfectly legitimate point of view. But it is also legitimate to take the opposite point...

Demystifier reacted to PeterDonis's post in the thread Graduate Resolution of the Frauchiger-Renner paradox with Informative.
But B also has to be entangled with things outside of F's body--the information about what B observed has to come from somewhere. So...

Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Let me make some side remarks on decoherence. That's why, in actual experiments, systems are cooled down close to absolute zero, so...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.Yes he has, that's my main point. The brain B has observed a definite outcome, because B decohered due to interaction and entanglement...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.I don't think that the notion of "actual" decoherence makes sense. To explain what I mean, let us model the friend F as F=B+R, where B...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.In the context of Wigner type experiments, decoherence is not reversed during some time during which the friend thinks "I have observed...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.No. The interpretations that I discuss in the post explain why there is no contradiction. If you don't see how the contradiction is...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.@PeterDonis I don't think that any of this what you mentioned is essential. 1. The entanglement with the particle with spin doesn't...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.What do you mean by "I", and what do you mean by "many worlds"? The F does not see that F lives in a superposition. Only W can see that...
-
Demystifier replied to the thread Graduate Resolution of the Frauchiger-Renner paradox.I believe I understand now the Wigner friend type experiments very well. It's really much simpler than usually presented in the...

Demystifier replied to the thread Undergrad Was Richard Feynman's explanation of the twin paradox wrong?.I have written a paper on the role of acceleration in the twin paradox. In short, acceleration is not essential, but still there is a...
