The MWI is an artificial solution to the measurement problem in quantum mechanics. It's just a metaphysical fiction which doesn't help in understanding, say, the movements of electrons and photons in double-slit systems. It doesn't help in understanding what electrons and photons correspond to...

Quantum theory is valid at the level of instrumental phenomena. Since this is as deep as knowledge of the universe goes, then, in that sense, the principles of quantum theory are deep. However, whether these principles describe a level of reality beyond or underlying instrumental phenomena...

I remember dowloading and printing a sort of manual on this experiment. It was part of the undergraduate stuff done at MIT I think. (I didn't go there --- just got it online.) If I can find the printout, I'll post the link (if that info is on the printout). I remember it being a nice...

It seems to me that the issue isn't whether quantum theory is universally valid as a predictor of experimental probabilities. There's every reason to believe that it is. But to adopt MWI requires that one take quantum theory as a complete description of an underlying reality --- and there's...

The "idea of multiple characters that exist and don't exist" doesn't have anything to do with quantum theory, or superposition, as far as I'm aware. Characters that simultaneously exist and don't exist is just a contradiction in terms --- unless you further clarify/qualify what you're talking...

Schroedinger's Cat (SC) and the double slit experiment don't *explain* the quantum world. SC is an illustration of the measurement problem in QM, the inadequacy of the Copenhagen Interpretation, and the absurdity of talking about cats as being simultaneously alive and dead. The double slit...

I couldn't play the video. Maybe you can tell me what software I need to play it. In lieu of that, I have a question and some comments on your question. My question is, in what sense is an epileptic seizure a mystical experience? Mysterious certainly ... but mystical ? To comment on...

This seems like a good question to me. So, for my pedestrian understanding (that is, giving a physical interpretation to the OP's original question), is it ok to think in terms of the probability of detection at location x being proportional to the intensity of the incident wave at x --- and...

ttn, I'm not sure what the most recent exchanges in this thread were about. Anyway, I just read Bohm and Bub's, "A Proposed Solution of the Measurement Problem in Quantum Mechanics by a Hidden Variable Theory". I'm not finished rereading your papers yet, and am boinking this thread in the...

Point taken. Changes will be precipitated by experimental phenomena that current theories can't handle. It would be surprising if, say, BM could quantitatively deal with something that OQM couldn't ... wouldn't it? BM isn't predicting anything new, is it ? I agree, and I didn't. That's...

Without getting into a protracted discussion about it ... yes. The point being that physics, the enterprise of quantitatively accounting for the phenomena that nature presents to our senses, isn't a 1-1 mapping of physical reality --- and this is especially true of whatever reality underlies...

I don't know what you're trying to say. Would you elaborate please ?

I could very well be missing some (or the) crucial point. Another, slower, reading seems to be called for (not today, but maybe tomorrow). The structure that empirical results have (or which is imposed on them), and what can be said about an underlying reality from that structure, seems to...

It's a qualification. What's known of nature certainly seems to have a nonlocal character. But what's the extent of that knowledge ? Is it complete ? I don't think so. We can see peanut butter sandwiches (mmm, yummy), tiger's stripes, and elephant's toenails. :rolleyes: But the...

Ok, I've read the paper, and I agree with the conclusion that no Bell Local theory can be empirically viable. Does this mean that nonlocality is a fact of nature? Yes, but only in the sense that no Bell Local theory can be empirically viable. (At least for the foreseeable future.) This...
