Ruler-changes and Relative Velocity

الأصل · EN

Simple signal-propagation effects make receding objects seem contracted and approaching objects seem elongated. These effects are theoretically photographable, and are proportional in strength to the frequency-change in the object's emitted light. In a one-dimensional version of the "barn-pole" experiment, a "moving" object's photographed image can appear doubly length-dilated according to fixed-aether theory, but only singly length-dilated according to SR. This expected difference might be charitably described as a form of photographable Lorentz contraction.
