   Newton vs. Einstein

   Newton claims that gravity is a force, Einstein denies it: for him it   
   is not a force (it is something else).   
      
   It is obvious that both can not be right: if gravity is a force, Newton   
   is right and Einstein is wrong, and if it is the reverse Newton is   
   wrong and Einstein is right.   
      
   It can not be otherwise!   
      
   Einstein is newer and Newton is more "ancient", so gravity should not   
   be a force.   
      
   So how do we "measure" gravity with the dynamometer that measures the   
   forces?   
      
   If it were not a force we should not be able to measure it with the   
   dynamometer!

   [[Mod. note -- The simple answer is that (from the perspective of general   
   relativity) "gravity" is a fictitious force quite similar to "centrifugal   
   force" in Newtonian mechanics, arising from NOT being in a freely-falling   
   inertial reference frame.
