Note: The previous post was recently edited to say "un-uniformity".
Let's keep this REALLY simple. Assuming that the wire is neutral (no net charge) and that the wire is 1 meter long and that I have a length contraction of electrons, why should I get from that a uniform charge distribution when the electrons are drifting through wire (current)?
I would TOTALLY expect an un-uniform distribution, assuming length contraction applies to the bulk flow of electrons.
I STILL don't have an answer to my question as to what do the electrons actually length contract towards.
