   The universe is expanding because space itself is expanding.   
      
   And since space and time are intrinsically linked, maybe it is spacetime   
   that is expanding.   
      
   That would mean that time is expanding along with space.   
      
   Presumably, that means that time is slowing down.   
      
   How would you test that?   
      
   And, if time is slowing down it would make it look like the expansion of   
   the universe is speeding up.
