How about this .....why do cable makers insist on using coax type cable ?  would it not be far better to have conductors that are the same .......

I have heard some strange things but never cable directionality [unless pseudo balanced ]. 

just remember that electrons can behave as particles or waves ...and we normally use a probability curve to predict the position of said electron in its orbital .....As far as I can see theres still a great deal more to find out about sub atomic particle relationships  to glibly discount everything that some people think is impossible.
