Squirm sucker, squirm.
  
"But the ray moves relatively to the initial point of k, when measured in the
stationary system, with the velocity c-v" -- Einstein 
(Which is not a speed directly measurable with respect to the initial point 
of k when MEASURED in the stationary system).
 
ahahaha.. HAHAHAHAHA... hahahaha...

Thanks for the laugh, dork. You are funnier than Jan Bilewacky!!!
We'll be down to the nitty gritty of the empty set soon :-)
