One of the most perplexing aurguements in the history of Physics is
the supposed existence of the Aether. Or in other words
Aether is has to be considered as a media.
In radio terms it can be stated that communication can be carried by a
surface wave only if it travels along the line of different media
which in physics is unshakable. Thus many physists argued that
air itself must be considered as a medium in that surface radio waves
certainly exist and thus the case against the existance of an Aether
has not yet been proven, as the question of the two mediums involved
have yet to be identified.

In metals and plazma are the acoustic waves and the electric waves. In the
both are the two media: ions and electrons.
