   You are claiming that theories of physics can't make predictions   
   of what will be measured in the real world, because a mathematical   
   model has nothing to do with the real world.   
      
   Say, how ignorant is possible to be?   
      
   Consider the following:   
      
   The orbital time of a GPS satellite is half a sidereal day,   
   that is 43082.045250000 s measured by a clock on the geoid.   
      
   GR predicts that the orbital time measured by a clock in   
   the GPS satellite will be:   
     43082.045250000⋅(1 + 4.4647e-10) s = 43082.045269235 s,   
     that is 19.235 μs more than measured on the ground.   
      
   See:   
   https://paulba.no/pdf/Clock_rate.pdf   
      
   This prediction is confirmed by real measurement   
   in the real world:   
   See:   
   https://paulba.no/paper/Initial_results_of_GPS_satellite_1977.pdf   
   It is even better confirmed by 48 years service of GPS.   
      
      
   This is an example where GR gives a precise prediction of what   
   will be measured in the real world, and the prediction is confirmed   
   to be in accordance with real measurements in the real world.   
      
   Do you still claim that theories of physics can't give precise   
   predictions of what will be measured in the real world?
