Now, if that *isn't* what you mean by a 'mechanism', then please be more clear. What qualifies as a 'mechanism'? Can you give an example?
You say we see mechanisms all the time around us. Can you give an example and why you consider it to be a mechanism? And then tell whether you expect something similar to underly QM.
"no hidden variables" and mechanism can be/may be two different things. I need to see more about what space/time is. For now, our models are only based on the outcomes that we see.
see "how small is it 05" for what I mean as a mechanism.
A simple example would be watching a city full of cars from some altitude where you can't see people. maybe even speed the time scale up so they are moving at a speed where we can't see people. A math model could describe how the cars are behaving very accurately.
The missing mechanism is people living. The "no hidden variable" would be 'sometimes they suddenly crash into each other for no explicable reason". We can predict the number of crashes over time but we can't predict any one crash specifically.
Keep in mind, I only say "I think there is a mechanism.". I am not certain.
Can you offer one piece of evidence that there is none? Just one please?
Well, it is still far from clear what you mean by a 'mechanism'. Without understanding that, I cannot give evidence that there is none.
You say that 'hidden variables' and 'mechanisms' may be different things, yet you fail to explain how. Then you go off on spacetime, which seems beside the point to me.
How is the demonstration that there cannot be a hidden variable theory that explains the observations NOT a demonstration that there is no mechanism underlying QM?
Your city analogy *does* have hidden variables: the people and cars operating locally and causally. That is explicitly refuted by the violations of Bell's inequalities.
