O’Barr comments: 
 It does not matter whether you want to talk about  
 SR or GR.  These two theories are the same theory.   
 Thus, SR is GR, and GR is SR, in the limit where SR  
 applies.  Therefore, if SR is just a math theory,  
 then so is GR.  If SR is weak as a theory in the  
 domain that it applies, then so is GR weak in this  
 same domain.  What is a true failure for SR, is a  
 true failure for GR.  Again, this is true as long as  
 you are in the limit where SR applies. 
 You cannot escape any of these relationships.   

 Maybe you did not see what I wrote above, where  
 it was clearly explained that SR’s 4-D spacetime  
 continuum is presently not a scientific concept.  And  
 I assure you, if SR is nothing but a simple 3-D  
 space, 1-D time reality, then so is GR.  It is  
 physically impossible to have reality change from  
 being simple 3-D to being 4-D, just because you have  
 added gravity gradients to your reality.      

 In reading your article on SR, these 3-D and 4-D  
 relationships, and absolute and relative  
 relationships, are not presented in any scientific  
 way, but in a political way, and it is not good  
 science.  Math is very powerful and important, and  
 the use of 4-D math in SR and GR should be taught and  
 used.  But no one needs to think that the math is the  
 physics.  That is ludicrous, unless and until a test 
 can be found that can distinguish these concepts.   

 Thanks for reading.
