The relative : motion is the relevenat factor. If the observer of the rod : accelerates instead he will see the same contraction of the rod as : when the rod is accelerated while he stays put. Because of this the : foreshortening of the rod cannot be due to anything other than the : change in perspective of it. What this means is that by raising the : velocity of the rod to greater than zero along its length, then our : perspective of the rod must change. What has really changed is not : the proper length of the rod, but rather its simultaneous length. : Observers in K and K' don't agree about the simulatneous length of the : rod, but both will agree on its proper length. Incoherent raving lunacy. In fact, relevenat incedental simulatneous incoherent raving lunacy.
