 It is exact to the precision of measurements, which is all one can 
 expect of an experimental confirmation.  

 And, I might add, certainly close enough for Positron Emission Tomography 
 (PET) scanners, lest your naivete or the usual propaganda lead you to think 
 relativity is only relevant to nuclear weapons. 

 Note followups to sci.physics.relativity; change to sci.physics if you 
 wish to discuss nuclear instrumentation further.
