I was behind the iron curtain until i was 13 years old so now i understand why we got the communist publications.

Surprising how you like to draw firm conclusions from a a few lines of words. I have read the Righteous Mind too. Something interesting about Engineering and Psychology difference is you need to read a lot of books to understand Science and Engineering, while for Psychology some people were just born with the knowledge in his head.
No, that does not happen at current densities that insulated wires can support.
It happens when current densities exceed specific thresholds, 10 power 6 0r 7 amps per square cm for copper. 10 million amps /cm^2 is what, 100 kilo amps in an AWG 12 wire. It is a consequence of momentum transfer, the electrons gain sufficient energy to bounce an atom out of the lattice.
It's quite well understood, and certainly does not happen at room temperatures for audio interconnects or speaker runs. I do worry about this for the solder interconnects between superconductors, but I'm running a kilo amp through #16 AWG sized wires
Wiki has a reasonable write up on this.

HV transmission lines typically have aluminum outer conductors spiraled around a steel cable. The steel supports, the aluminum conducts. When they make the cable, they draw the bundle through a die such that the aluminum wires are pie shaped and the outer surface is more of a cylindrical shape. That reduces external field gradients for higher voltage use.
As to temperature being less of a problem, remember the NE blackout IIRC was caused by overloaded high tension lines that heated up, sagged too much and touched treetops.

I wonder why there is little/no data on this from the scientific community. Experiments are typically instrumented until the noise/confounders are at or below what is computed as the minimum possible from the physics of the experiment.
We had a big customer that wanted us to do a remote sag monitor. They wanted power and data via optical means (for obvious, 750kV, reasons). In talking with them it was apparent that this was a if not the major issue.
You did not use high purity dead soft annealed did you?
What I meant was a change of property of a wire resulting on a perceivable sonic difference in a domestic audio chain should be measurable.

It is, he heard it, haven't you been paying attention
You must have heard the quote from Toole Planet 10 trots out at every opportunity.
Subject to new scientific discoveries concerning the properties and constitution of conductive materials, I am, of course, of the same opinion.
Anyway, John has mentioned that silver cables produce, on his experience (that I do not question), a "brighter sound".
In everyone's mind, this implies a modification of the response curve with a relative increase in the level of the treble. We (he) know how to measure that. If this proves to be effective, it is advisable, in a second time, to explain the causes.
If it turns out that the measures contradict this impression, we have to look at psycho acoustics. Silver is often considered more brilliant for two reasons,OMHO.
The first is its color, white being considered more "light" than dark red.
The second, that some tweeters whose moving coil was made of silver go higher in frequency than their copper counterparts. This is, of course, because Silver being better conductor, the weight of the moving coil can be lower for the same resistance.

That could have an undesirable result of placing it squarely as the mundane and lost the aura of mystic. Blame Tolkien and Rowling.
It would be measurable if it existed, there has been no evidence presented that would survive reasonable scrutiny.
He was wrong about that, IMHO.
Regarding Science, Natural Physical Science is perhaps the term you were looking for (from the Wikipedia article you linked):
"Natural science is concerned with the description, prediction, and understanding of natural phenomena based on empirical evidence from observation and experimentation. It can be divided into two main branches: life science (or biological science) and physical science. "

Not really. Most people mis-read Kahneman, some more so that others. Apparently, some do to an extreme.
Personally speaking, my science and engineering library was far more extensive than for any other subject. The rows of bookcases are long gone, the internet having made paper copies unnecessary.
You need to look for asymmetric current noise properties, standard full wave rectification sensing will return averaging results.

There is signal frequency dependent velocity behaviour (dispersion, Hawksford) which causes resonance and dynamics behaviour anomalies and PIM.
