Reality (General)

DAVID: Both regions [i.e. individual quanta and combined bus quanta] are just as real as you want, but vastly different. (dhw’s bold)

dhw: […] I agree with your conclusion (bolded). My disagreement with Kastner was over the claim that the behaviour of the “raw materials” was MORE real than that of the combined materials. My disagreement with you was over your statement that “quantum mechanics is the basis of reality”. […] All we can agree on, as you so rightly say, is that the two forms of behaviour are real and vastly different, and nobody has yet found an explanatory link.

DAVID: I sense we are in a degree of agreement.

dhw: We are indeed. Out with Kastner’s “more real”, and let’s leave a question mark over your claim that the incomprehensible behaviour of individual particles creates the perfectly comprehensible behaviour of particles en bloc.

My continuing disagreement with part of your approach is that the incomprehensible particle behavior somehow does create our reality. We may not understand it, but we should recognize the relationship.


DAVID: As an example of quantum experiments read the following brief summary of a quantum experiment:
https://theconversation.com/quantum-physics-our-study-suggests-objective-reality-doesnt...
QUOTE: "[…] In other words, according to our best theory of the building blocks of nature itself, facts can actually be subjective."

DAVID: And as you read the rest you will understand the confusion everyone feels about the particles that create our reality.

dhw: I know all about the confusion, which is why I object to definitive statements about the basic role played by quantum mechanics in the creation of our everyday reality, and a few days ago I pointed out that nobody knows what “objective” reality consists of because our perception of it is always subjective; the nearest we can come to objectivity is consensus. And consensus has it that the behaviour of the bus and of the quantum theorist it hits is as close to objective reality as we can get.

I have the same objection as above. Quantum reality underlies our reality. There is no getting around it, but it is true we can make no definitive statements about how it works..
