Re: Park City Paradox ?

[Robert Cohen <Robert.Cohen@PO-BOX.ESU.EDU>]

Aren't you saying the same thing I was saying?

We agree that no separation is observed when the two electrons move side by
side at v=c?

Saying that this is because "time stops" or "the magnetic field counters the
electric field" or "the information can't catch up" -- aren't these the
same?
