   I'll tell you what I understand clearly and what I don't.   
      
   Of course, I understand that in my world the rigid body remains rigid   
   and does not become flexible just because it moves at some speed,   
   because speed does not act either on the size of bodies or on their   
   rigidity.   
      
   Having said this, I am also ready to accept that at very high speeds   
   (close to that of light) exceptional phenomena can occur, such as the   
   contraction of the length of the body or the loss of its rigidity.   
      
   However, before I really believe it, I would like there to be at least   
   some proof.   
      
   So I ask you: has the contraction or loss of rigidity of a body in   
   relativistic motion ever been measured?   
      
   If such a measure never existed, I would have to believe in this   
   phenomenon only by faith and I am not a believer.

   This is not a demonstration or even proof.
