But logic and laguage come to the rescue when something like a field is defined as a region wherein a specific thing happens. The field becomes the ontological element.
For someone who argues that meaning should be set in stone, it is ironic that that isn't what ontological means. Here is the relevant extract from Newton's General Scholium:
Isaac Newton wrote:Hitherto we have explain’d the phaenomena of the heavens and of our sea, by the power of Gravity, but have not yet assign’d the cause of this power. This is certain, that it must proceed from a cause that penetrates to the very centers of the Sun and Planets, without suffering the least diminution of its force; that operates, not according to the quantity of surfaces of the particles upon which it acts, (as mechanical causes use to do,) but according to the quantity of the solid matter which they contain, and propagates its virtue on all sides, to immense distances, decreasing always in the duplicate proportion of the distances. Gravitation towards the Sun, is made up out of the gravitations towards the several particles of which the body of the Sun is compos’d; and in receding from the Sun, decreases accurately in the duplicate proportion of the distances, as far as the orb of Saturn, as evidently appears from the quiescence of the aphelions of the Planets; nay, and even to the remotest aphelions of the Comets, if those aphelions are also quiescent. But hitherto I have not been able to discover the cause of those properties of gravity from phaenomena, and I frame no hypotheses. For whatever is not deduc’d from the phaenomena, is to be called an hypothesis; and hypotheses, whether metaphysical or physical, whether of occult qualities or mechanical, have no place in experimental philosophy. In this philosophy particular propositions are inferr’d from the phaenomena, and afterwards render’d general by induction. Thus it was that the impenetrability, the mobility, and the impulsive force of bodies, and the laws of motion and of gravitation, were discovered. And to us it is enough, that gravity does really exist, and act according to the laws which we have explained, and abundantly serves to account for all the motions of the celestial bodies, and of our sea.

An object only exists as an ontological object or a thing because we gave a name to its particular properties. When we give the property of gravitation within a region a name, it becomes a thing, an ontological element ("gravity field"). Without the name, we can't speak of it as a thing, whether it is there or not. We can only speak of the named things around it that might be the cause of the properties (or that property might be the cause of them - which actually turns out to be more true).
A gravity field is a part of the nature of being uniquely distinguishable from other parts and thus an "element of".
So how is a gravity field NOT an ontological element, a "thing"?
What is causing that field is another issue. I haven't gone into details concerning that, but it certainly has a cause, merely waiting to be appropriately named. And I have given it an appropriate name.
uwot wrote:Long story short, for the purposes of physics, it doesn't matter that you don't understand the cause, "to us it is enough, that gravity does really exist".
As long as you don't want to know any more than that. Why not just say "God does it"?
God is not an ontological element in science, NOT because of any suspicion of nonexistence, but rather because as an ontological element, it answers no questions, gives no details that can be used for predicting critical concerns (the very purpose of science).
Now you are doing the same thing as religion: "
Gravity just is and acts. Don't question it! You don't need to know."
uwot wrote: The gravitational field is where things are attracted, this attraction can be measured and described mathematically, so we know what happens, but to this day, we don't know why.
And the way you are talking, you will never know why. I am in the midst of explaining WHY (the "metaphysics") while also explaining how to MEASURE not merely that gravity, but ALL existence (the "physics"). Of course you can already do some of it without understanding what you are trying to measure. But you also get all confused because by not understanding what you are measuring in sufficient detail, you imagine that you are measuring things that are not there, giving them names, and extending theory into fantasy.
uwot wrote:It seems to me that you have created an hypothesis out of your belief about what happens, granted you have supported your claims with some neat graphics based on your own mathematical model, but I don't remember seeing any physical evidence that this is how it works.
You don't "see the evidence" before you know what it is that you are talking about. Again, one who argues the existence of God without even knowing what a god is. We haven't gotten to the empirical evidence yet. We are just now talking about the necessary LOGIC behind an upcoming hypothesis that hasn't even been formed
YET.
You keep trying to think, "Well I already know most of what is going on. And you aren't agreeing with what I already know." And that would be fine is I was merely trying to ADD to what you already believe. But I am starting from SCRATCH. What you think that you know is irrelevant at the moment.
I am discussing the very beginning of understanding, not some theoretical appendage to your beliefs.
uwot wrote:You can create any number of models to explain certain phenomena
And you can bitch about every one of them until you are blue in the face. Until you examine the
logic being presented, you know nothing and contribute nothing.
Understanding doesn't begin with observations of the unknown, but with
defining its affects then
measuring them. Gravity within a region, a "gravitational field" is one of the affects of that unknown universe out there. So give it a name and define it.
uwot wrote:why should anyone change?
So they can learn more than they already know (believe).
Why not just stick with Christianity and the Bible?
uwot wrote:JSS wrote:QM doesn't deal with physical anything. QM is strictly about mathematical probabilities and equations as "objects".
Well now, here is another irony: quantum field theories, QED, QCD, Higgs, are all premised on the assumption that 'particles', real and virtual, are disturbances in actual ontological fields.
Tell that to the "collapsing waveform", "particle wave", and "entangled particle".
