   No.  Instead, the energy density of the classical electromagnetic field   
   ought to contribute to the (stress--)energy--momentum tensor which   
   corresponds to the curvature of spacetime (AISB).   
      
   Do not listen to Stefan Ram who is an incorrigible wannabe who (by contrast   
   to me, in this case) has NOT studied physics (or anything, it seems) *from a   
   professional*.
