You totally did not get my comments. I found no problems or errors with the links. That’s why I said quoting ANY scientific explanation is like saying the sky is blue. Just because a statement is true doesn’t necessarily mean it supports a given proposition. The reason I said e=mc2 helps explain my proposition regarding how the audio signal works is because that particular equations includes the term c which is the speed of light. We know for sure that photons are the only particle that can/must travel at the speed of light in a vacuum, so we can probably conclude current in wire or in free space is composed of photons. Now, I’m not saying that proves anything about directionality, but first things first. If you can find a scientific explanation or equation that indicates or provides evidence why directionality cannot be real I’m all ears.
Pop Quiz 2 (free tweak for first correct answer) - If it’s true that photons have zero mass why is it light cannot escape a black hole?
