How Electricity Actually Works

I think the simple answer to "Does this have implications for audio cabling" is no.  I didn't see anything in the presentation that would make a whit of difference anymore than it would to television,  refrigeration, lighting, power recliners, coffee machines or any other electric devices in your house. I can't understand why some watch these videos and then go off into the twilight zone of cables. The Therory presented here hasn't changed since 1978 the only thing that's changed is we have the internet and the ability to explain these phenomena outside academia has improved.

Strange how my speakers measure and sound extremely well. No hiss or hum my ear within an inch of the tweeter or mid yet my power cable and balanced cable run parallel, even strapped together with velcro for a distance. The way some think here nothing should work or I should be getting nothing but distortion. My cables are generic nothing expensive or special about them maybe that's the reason everything works and sounds great? 

This does have implications for our audio cabling...

I haven't seen anyone explain how...does it have any implication for wireless speakers? 

Energy does flow in the conductor, if it didn't the wire wouldn't get hot. Current doesn't leave and return, charge flows, current is the measurement (time) of the flow ( Quantity of charge) through a cross section of the conductor.

Electrons flow?

I never said electrons flow, though they do drift. This thread is a discussion about the weirdness or non intuitivness of electricity not the audibility of fuses and wires in sound systems. You like Feynman, here you go.

While you're at it you might want to brush up on what a scientific Theory is, it's not Billy Bob Bodine guessing why beer has bubbles.

We as a species don't know a tenth of a percent about anything? Pretty pessimistic view of Homosapiens.

Lucky for those in this hobby we've managed to blindly stumble upon enough to record and reproduce that recording to an amazing accuracy. Good thing it didn't require us to dissect the Universe. 

Then there's hope,  since they way cables in audio works is self evident to most people.

The electrons have to fight their way along the wrong direction, and have an easy path going the right way.

?? What the crap? Maybe that's why electrons only drift about .02 micrometers in AC they're always confused as to the right direction.
