"1Z": > Why shouldn't it just *be* time ? A structure evolves from state to state in a regular way. The fact that an observer built of that structure inside that structure can formulate mathematical descriptions with a "t" in them that correlate well with what is observed does not mean that there is anything real in t any more than it means anything else in the maths is reified. Time is yet another 'as-if' construct. The universe (the structure) behaves as if a t was there when it's just an artifact of models.

The experienced moment to moment progress of the state of the structure literally is what we perceive as time.... in the sense that there's no special entity pouring some 'timeness' into the structure. A metaphor experience for this occurs when you write industrial 'real-time' control software state machines. You can make the control system speed up and slow down (meaning that the control system sees the world slow-down and speed up, resp.) based on the rate the state machine is executed. > > > > > > >> and that it's appearance > > >> as 'physical' is what it is like when you are in it. .ie. > > > > > > Presumably, what is *necessarily* like when you are > > > in it , since there is no contingency in Platonia. > > > > Platonia has not been instantiated.

No. They are descriptions of observations formulated by observers of 'the relational structure'. To an observer built of the structure inside the structure bits of the structure behave 'massly', gravitationally, electric field-ly, space-ly and so on. If the mathematics ca, in some sense, termed an expression of relationality, that's just an artifact of the maths, not a statement about the original structure exhibiting the behaviour. > > > All the same...and > > none of these have been predicted by any abstract model or > 'lumpy/thingy' > > ontological thinking. > > The physics we have is structural/relation from > top to bottom.

Yes, and none of that physics says anything at all about the intrinsic structural nature of the entities portrayed by the physics. The are descriptions of behaviour (WHAT HAPPENS) that correlate with observation. Correlation(WHAT HAPPENS) is not causation(WHY IT HAPPENS). Causation is what is happening in the underlying structure. Again: the universe is behaving 'as-if' physics was driving it to an observer inside the structure, of the structure. > > The question is what can futher be predicted from that.

It behaves with amazing amounts of regularity (even the persistence of randomness and chaotic behaviour is regularity!). The regularity as perceived (in the first person!)...that orderliness...correlates well with some models and not others, at some scales and not others. These models are descriptions only and are not explanations in the sense of causality. > > Time, in particular, is not a mere mathematical construct.

Well I agree that it doesn't exist. See above....it's virtual. I disagree that it's hard. It's the most simple intrinsic property implicit in the evolution of the structure we inhabit. The causal options for the intrinsic state transitions of the structure limit the next state to be a specific thing. The limit makes the structure evolve as it does and it does this in a regular way (one direction). It's only hard because no mathematic model (progressing theorem evolution) actually progresses from proof-step to proof-step without being driven by a mathematician or the preempting of a theorem proving model provided by a mathematician. > > > > Timeless universe, universes where everything that can exist > > > does exist, are not well founded empirically. > > > > No they are not.

"Schordinger's equation" is yet another model of the structure, not the structure! What exists is the structure! Because the maths implicates the impossibility/possibility of something or the idea of multiple universes or anything else _does not mean_ that the structure that the equation describes will necessarily incorporate those ideas. It means that the structure acts 'as-if' it did to observers inside it, made of it. See a pattern here? This is all the same from one end to the other. This is a fundamental cultural blockage we inherit because we have all been brought up to worship abstract mathematics and its 'unreasonable effectiveness' with an almost god-like deference. > > > Only that the > > model makes it look like it does.

A resounding so what! Nobody told the universe its structure had no interesting proprties...it seems to be trundling along nicely producing people/observers who can define words like physicalism, which is kind of interesting, isn't it?
