One of the most perplexing aurguements in the history of Physics is
the supposed existence of the *Aether.

It has been proven that "empty space" is indeed not empty and consists
of quantum particles that wink in and out of existence. Aether does
exist as a sort of quantum soup, just not in the limited form that was
earlier conceived in the past before quantum physics. The Casimir
effect is a manifestation of the quantum soup that exists in "empty
space". Some physicists think that's where the dark energy is hiding.

Whoa!You are talking apples and oranges. The two mediums discussed is
in actuality mass and particles where as it was considered as mass and
the Aether. I am certainly aware of the term quantum soup outside of
the Earths confines!
The two mediums of a radiator and particles is what provides for
ground wave and connected to
propagation. I don't think the scientists of the day were considering
propagation in outer space but I am willing to read any article that
supports your position
There are many positions and counter positions on the subject given by
most of the masters of the day.
