I'll stick my neck out and say. A thin rod forshortens obeying the
inverse square law as its size gets less and less as it accelerates. A
rod twice the diameter of this thin wire has to move twice as fast to
have the same measurement. Trebert


Herb, SR says that the observer dependent foreshortening obeys
this equation:

l' = l_o/gamma

where gamma = (1-v^2/c^2)^-0.5

So one can see from the equation that distance is not a factor,
but the relative velocity between object ans observer is. This
equation is valid for an accelerating object also.

Equations, like this one, are compact statements about the way
nature works, expressed in the language of mathematics.

May I remind you about your buddy's, Einstein's theory--There
has never been a prediction of special relativity that was
contradicted by an observation. You choose some pretty smart
friends, Herb!
