Perceptions are specialized and easily tricked.
Recall that I was talking about recognizing illusions; how do we discover if our perceptions have been tricked?
If A is an illusion that looks like B, it seems clear by your terminology that the illusion of B is real... but is B real?
Is curved space real?
Is there anything that satisfies the proposition "X is not real"?
From there we can build artificial senses (atomic force microscopes etc.) and logic systems to understand aspects of the causality of the system.
So theory and experiment may, indeed, suffice as replacements for direct sensation. Allow me to set this idea on the back burner a bit before we go into depth how this may be done.
But allow me ask one question; if it takes much more than a "yes" or "no" answer, we can defer it until later... is it ever acceptable to trust these artifical senses and logic systems when they contradict our senses?
For example, in the famous optical illusion of circles surrounded by circles, is it acceptable to trust the ruler (and implicitly the theory that rulers are good measuring devices) when it says they are the same size, despite my vision telling me otherwise?
When I say "matter in motion" there is a tendency to imagine a kinetic-atomic model of atoms (or objects) bouncing around in a void. This is not what I mean. I am talking about matter as a compressible fluid-dynamic frictionless continuum--in turbulent motion, compressing, rotating etc.
I'm avoiding ascribing
any physical idea to "matter in motion" at this time, for the purposes of this discussion. I'm talking neither about bouncing balls nor flowing fluids; I'm trying to develop an acceptable framework of discovery which we can use to make this discovery. Might "time evolution" be an acceptable synonym for "cause and effect"?
Root-level matter is the continuum mentioned above and atomic matter is formed by ...
To avoid fixing the discussion to anyone theory (and to better follow the flow of the discussion so far as to determining what is an acceptable way to understand the universe), would it suffice it to say that you are using the term "matter" both for "root-level matter" (which is, in some sense, fundamental) and for observable patterns of that root-level matter?
Matter is extended and this extension is real. "places" are real therefore as well.
Is there any way we could deduce this conclusion from observation, or must we accept it as an axiom for this discussion? And would the term "point" be an acceptable synonym for "place", in the sense we can say that the universe is "made" of points, and matter extends through these points? By "made" of points, that just means that all extensions of matter can be described by the points through which it extends.
Yes, in raw matter they are unequilibrated density deviations...either positive or negative (also known as charge).
This is in accordance with my previous comment on the term "matter" correct; pressure is not fundamental matter, but an observable pattern in root-level matter. Allow us to hold off on more precise meanings of pressure.
