Since you are so familiar with the concept why not start from Earth

to your favorite "dark matter" For that matter explain what a "medium"
is in physics terms.

Art, you don't seem to understand that there is a quantum base medium
to which some other medium may or may not be added. The base medium
exists throughout all of universal space and is the only medium that
exists in otherwise empty space. Any other added medium, e.g. air or
water, is just mixed with that base medium. Please stop thinking with
a concrete brain.

In the "physics terms" the base medium is Dirac electrons see.
The "added medium" are ions, atoms and dust. All are produced by Stars.

The same mixture is in metals. In metals the free electrons are medium for
the electric waves and ions and atoms for the acoustic waves.

Maxwell-Heaviside ether was like the dielectric.
The todays ether is like rare plasma. Plasma is a conductor.

Just when I thought you were getting it too ... you need no dust, no
matter which you can touch, to have emf produced and transverse-ing the
universe(s.) See, you are still focused on that "surface."
