   The answer is very simple.  We choose models that can be "understood"   
   by our normal senses, leaving us with a warm fuzzy feeling.  Models   
   that make sense to us are based on our everyday observations.   
      
   However, the properties of light do not fall within our normal   
   experience, hence we are unable to construct the perfect model.   
   Neither wave nor particle theory is correct.  What is correct is a   
   mathematical description (which is outside our normal understanding).   
      
   This does not mean that we cannot understand the theory, just that it   
   does not fit a simple life experience model.  It is futile (in almost   
   all subjects) to vociferously support one model over another.  The   
   better model is always the one that best fits the facts and best fits   
   our life experience.   
      
   So, in answer to your question, neither theory is correct.   
      
   Much wasted time could be saved if this simple concept would be explained in   
   schools.

   P.S.  Philosophical question:  We adapt to the universe, not the other   
   way round.  Or does the universe adapt to us?
