TBG, why do I persist? Maybe it is the 'educator' in me.
Your staement that all objects fall at the same rate ONLY in a vacuum is WRONG. Identically shaped and sized objects of different weights (actually mass) fall at the same rate regardless of whether there is a vacuum or not.
I think Galelleo demonstrated that a long time ago.
Take two basket balls and fill one with water and drop both from a height. They both will drop at the same speed.
You, however, might witness that the heavier one hits the ground a little ahead of the lighter ball and conclude that the scientific explanation is wrong or simply say that 'I know what I saw, therefore science can't explain everything'.
It has been proven over and over that the human senses are very unreliable.

PS. I have never heard a difference in fuses or proper wires for that matter, but I do hear a difference in sound when I move my ears less than an inch, so my hearing acuity is not in question.
