Doesn't the word spontaneous
refer to unpredictable events? Aren't they called spontaneous because we can't predict or precisely explain them? Nevertheless, even so called spontaneous events are differentiated wrt, and predictable within certain bounds, wrt certain antecedent conditions, even wrt quantum experiments.
Determinism is an assumption. If one assumes it, then lack of explanatory or predictive ability is due to ignorance.
The assumption of indeterminacy doesn't seem to fit with our observations of the basically orderly, and predictable, evolution of the world, the universe.
Degrees of freedom wrt what? Where do the constraints come from?
In a certain view, it (everything, anything) starts with (is ultimately attributable to) a fundamental wave dynamic ... something that the behavior of any and all disturbances in any and all media at any scale have in common.
This fundamental wave dynamic is what constrains
the evolution of the whole and determines the emergence of discernibly bounded systems (ie., particles and objects).
In a certain view, a fundamental dynamics determines the bounds and possible evolution. Spontaneity isn't, in this view, intrinsic or fundamental. It just refers to our ignorance.
Why not assume a fundamental wave dynamic and see where it leads?
And by the way thanks for your and others' replies to my previous questions/comments.
