You’re imposing a Newtonian physics on the quantum field. The answers you are looking for are somewhere in the math, string theory or the standard model or maybe something new, but saying quantum fields “is a volume containing physical things” is definitely a step in the wrong direction.
I don’t think so. If fields are not physical within volume then what are they? Nobody knows what a field “is”, really, it is sometimes described in very rough analogous terms as a fluid-like substance.
Sometimes I wonder if making computer models of a vacuum, one that contains no particles, nothing that we interact that, then displaying it with colors and something bouncing around on the screen, actually just confuses people. It takes a concept of no physical anything and displays it as something with form.
To say the vacuum is "no physical anything" is again, I think, incorrect. The vacuum must be something, else it would be absolutely nothing at all, in which case it would not be a vacuum. The vacuum is all fields in balance, no curvature.
Gravity may be expressed as a curvature of space, with the classic 2D analog being a sheet of elastic material stretched out with a weight in the middle of it causing another moving object, say a ball rolling along the surface, to “naturally fall” in a curved path toward the weight that is causing the depression in the elastic material.
But what is the true material that gravity curves? It is the vacuum, space. Space is a material, or more likely a sort of “solution” of materials. Absent an electric charge, or a magnetic dipole, or a mass, or a nuclear particle the materials that is space are all in balance, not “curved”, no “density” gradient. But in the presence of these sorts of things each respective material in space takes on a curvature in 3 dimensions.
The display is fields interacting with each other, not anything with form or mass.
If, for example, the presence of mass curves space then space has form, the curvature induced by the presence of mass.
It seems then that space is a superposition of perhaps 4 materials that are curved independently, each by different sorts of things, giving rise to the 4 known forces of nature.
Did you watch the lecture on page 3?
Sorry, I could not locate that. Did you provide a reference? I went back up the thread and did not see it, maybe it is time to get stronger glasses again :-)
But yes, the universe is entirely mechanistic, no poof whatsoever.
