I'm afraid people who believe cables transfer more than electrical signals aren't very scientific to begin with.
If anything audio cables transfer
placebo particles invented by snakeoil sellers.
Also, expensive audio cable are known to transfer a lot of money from buyer's wallet to the bank accounts of snakeoil sellers.
The real frequency response is the Fourier transformation of the system's impulse response. It is
complex-valued. It has amplitude and phase. Plotted frequency responses are almost always only the amplitude while the phase is omitted. This loses a lot of properties of the system. So, there are lots of stuff that we can't see in an "amplitude only" absolute value frequency response plot, but that doesn't mean we can't measure those. Impulse responses are theoretically full descriptors of a
linear system. Complex-valued Fourier transformations simply take impulse responses from time-space to frequency-space (it is kind of like watching an object say a car from 90° different angle: You see different things, but it is the same damn car!) so no information about the system is lost.
There are four known forces of nature:
The strong force (keeps atom nuclei together)
The weak force (causes radiation)
Electromagnetism (electricity, magnets, light...)
Gravitation (makes apples fall into your head when you sit under an apple tree)
Recently scientists have gotten results while studying
muon particles (similar to electrons in other ways but about 200 times more massive) that indicate there might be a fifth force we don't know about because muons don't obey completely so called standard model which otherwise has made astonishly accurate predictions. However, I doubt it people scientifically illiterate enough to buying into the nonsense told by snakeoil sellers would know more about this possible fifth force of nature than top scientists in the World...
