I can see the "spirit" you said that in, however, that statement could
not be further from the truth ... "it" (or "those" theories and
"ponderings"--space-structure/ether) is the whole reason why a signal
gets from point a to point b ...

We cannot know if there are possibly better ways to manipulate
this/these mediums, or if it is possible to design antennas "better" to
manipulate "it", until we know what "it" is ... barring "dumb luck" and
someone just "stumbles" onto some antenna which shows some improvement,
somehow.

But yes; build something from present-day data/technology, it looks as
if all this is going to take a bit before we know.
