I want to thank you, perhaps more than any other I have talked to here the last few day, for your patience, effort and time invested, thoughtfulness and kindness in discussing these things with me.
You're very welcome.
You say, "An 'explanation' that raises more questions than it purports to answer, especially if those questions are unanswerable, explains nothing." --I'm not sure that's true. Certainly Quantum Physics as we know it raises more questions than it answers, (that is, unless you want to combine them all into the catchall, "HOW?"), since we hardly know where to begin asking the questions or what words to put to them.
Unless you specify the relevant quantum physics phenomenon and the proposed explanation, I can't really comment specifically; but you may have misinterpreted the point, which refers to the explanation alone, rather than the phenomena or entities invoked in explaining (though an understanding of the phenomena and entities involved can obviously help).
For example, if you asked me how an internal combustion engine worked and I said 'gas' or 'fire', you would rightly say that was no explanation - you'd want to know
how gas or fire caused the engine to work. All you'd need to know to understand how an internal combustion engine works is that gas can make fire and fire can heat air in closed cylinders causing it to expand, pushing pistons that rotate a crankshaft that transfers torque to an output shaft, and so-on. Of course, there are always more possible questions to ask - how gas is flammable and how combustion occurs, why air expands when heated, how the piston is sealed, etc., are secondary explanations - a minimal explanation gives a basic understanding of the operation of the machine.
A meaningful primary explanation must be in terms of what you already know or understand (e.g. air, heat, pistons, crankshaft, torque).
If you had a basic understanding of physics and engineering, i.e. you understood the relevant secondary explanations, and you had a description or example of an internal combustion engine, you could figure out how it works for yourself.
I should also have mentioned that a consequence of having to provide a deeper understanding of particular phenomena means that an 'explanation' that can 'explain'
anything doesn't explain particular phenomena. For example, saying that particles, forces, and fields explain everything, is not an explanation for how an internal combustion engine works - it's not even a secondary explanation.
You should be able to see now why "God-did-it" is not an explanation as it stands. It fails on all criteria.
In quantum mechanics, we have a precise mathematical formalism that enables us to calculate, with extreme precision, the probability of seeing a particular outcome of a quantum measurement or observation.
We don't claim to have a physical explanation of what the mathematics means (although there are various interpretations), so the formalism is a mathematical explanation for quantum observations.
I don't know if I lack the intelligence to see what you have shown, but I have not seen you posit any other possible explanations for existence --only to mention other avenues of study that exist. Of course, my saying that doesn't render them invalid.
I've mentioned possible histories of our universe, consistent with known physics - temporally infinite histories, mirror time histories, and finite-but-unbounded-in-time histories. They're currently untestable, but they're possible explanations.
"To avoid using the the term "God", as I said I would do, I will say First Cause, but the explanation, "It's magic!" doesn't do the job because magic requires no intent, no direction, and possibly implies the rule of chance, which is illogical nonsense. To me also, it seems to only send one down the road of infinite regression --another logical fail.
A 'first cause', per se, is just an initial event; so, unless the capitalisation confers some additional meaning, it also has no intent and no direction - assuming it's necessary at all.
I don't know what you mean by the 'rule of chance' being illogical nonsense, or why it results in infinite regression, and why that's a Bad Thing - you'll have to explain that.
I'd also like you to explain why you think intent and direction is relevant - what, exactly, requires intent and direction? intent to do what, and what needs direction?
And you still didn't answer the question asked - how does it (God)
satisfy those criteria better than the non-explanation, "It's magic!"?
Those criteria are commonly used for assessing explanations - if you prefer, how does it satisfy those criteria
at all ?
The Cheshire cat reference was only an attempt at humor, derived from your handle and from the claim of some that quantum particles are observed causelessly blinking in and out of existence.
'Virtual particles' are just an analogy for below threshold quantum field excitations.
I hope I am not fooling myself to say that the special pleading for First Cause With Intent, is only after a long look at all the other alternatives semi-cogently presented to me so far. Perhaps it is special pleading, but if it is, I find it still more compelling than many other beloved premises of current scientific pursuits. But perhaps that is my bias. I do have a habit of appreciating my own thoughts more than they merit.
Special pleading is a fallacy, so an argument that uses it is, by definition, mistaken (whether the point at issue is true or false). If you're happy to knowingly hold with an irrational/illogical argument, that's your prerogative, but if so, rational argument and critical thinking are no longer relevant, so I'll stop.
When a person sees a gap, as we all do (I think) concerning absolute beginnings, we consider different probable explanations --gap fillers ... Yet we still don't know what Gravity is, nor what the smallest observable particle is composed of at its most basic level.
Inevitably, unless reality has infinite levels of scale, there will be unexplained fundamental 'stuff', out of which everything else is made, and which it makes no sense to ask of what it's made. The same applies to existence in general - ultimately, it's a brute fact.
But on the topic of unexplained existence, you previously said, "Existence begs explanation." I then asked you if God exists. You didn't respond.
You can see why I asked the question - if existence begs explanation and God exists, then God begs explanation. If you insist that everything that exists must have an explanation, then either God must have an explanation or you're special pleading again.
Alternatively, 'begging explanation' may be a wistful aspiration that acknowledges that not everything necessarily has an explanation; in which case, the universe (or multiverse/metaverse) itself may not have an explanation, making a First Cause redundant.
We only end up with Structure, it seems to me, not Filler. But structure is good, don't get me wrong. Yet I can't help but think that at some point we will see what was wrong with the periodic table --not just in depth of knowledge, but a presumption we did not realize right up to present day. And yes, that may be a flight of fancy of mine. But then, after all, Quantum physics has turned more than one presumption on its head.
I don't know what you mean by this - we know the layout of the periodic table is a compromise, but in what sense is it 'wrong'?
