   I understand that at least within the AdS/CFT dualities, exactly all of the   
   information,   
   characterizing the (N)-dimensional AdS bulk, maps into all of the information   
   on   
   the (N-1)-dimensional CFT ‘surface’.  And that quantum field theory lives   
   on that   
   CFT boundary.  But this boundary also contains no gravitation, which lives only   
   in the AdS bulk.  [And presumably, in some future de Sitter/CFT theory, the   
   same   
   thing would be true.]   
      
   But since all of the gravitational physics in the bulk must constitute some of   
   the   
   total bulk information, how can gravitation itself map onto the gravity-less   
   CFT?   
   Ie:  What precisely does the bulk’s gravitation “hang it’s hat on” in   
   the CFT   
   surface?   
   (This confuse Tarzan)
