   Not very useful, nymshifter, please explain more about tensors if you can.   
      
   Regarding tensors, since the spin of the boson corresponds to the   
   dimensions of the associated field tensor (does anyone know why/how?),   
   a spin 0 boson would have a zero dimensional scalar field (like   
   temperature of points within a volume), spin 1 a vector with a   
   direction, spin 3 and beyond would be quite interesting with 3+   
   dimensional tensors. What would this look like in real life?   
      
   Also how does spin 1 electromagnetism differ from (theoretical) spin-2   
   gravity? I know gravity waves are depicted as stretching in one   
   dimension while compressing at a right angle for a half cycle while emag   
   jiggles back and forth but beyond that?   
      
   [[Mod. note -- A "minor" nit-pick:   
      
   The term "gravity waves" has been used for hundreds of years in physics   
   to mean a wave propagating in matter in which the restoring forces are   
   provided by bouyancy and gravity.  E.g., ocean waves are this sort of   
   gravity waves, as are pressure waves propagating in the atmospheres of   
   planets and stars.   
      
   The spin-2 "ripples in spacetime curvature" that we're talking about   
   here are better called "gravitational waves".  I've heard the slang   
   term "gravy waves" for them, but this doesn't appear to be common   
   usage.
