When current flows through a material, electric resistance is observed when the electrons collide with the material's vibrating atoms.
My textbook says that when we cool the material till the point where the atoms reach a state of rest, the electrons will not collide with the atoms at all, and we can achieve zero resistance.
But how is it possible that we can have absolutely zero collision?
The analogy I have always used is to think about walking inside a train. When people are moving around inside the train, I can't move freely as I'll bump into them easily (high resistance). But even when no one is moving, I still can't move totally 100% freely, simply because their very presence is blocking me.
Doesn't the presence of the atoms themselves hinder the flow of current, even when the atoms are not vibrating?
