   We simply do not know that.   
      
   While it is correct to say that zero proper time elapses along lightlike   
   geodesics (ds^2 = +- c^2 (d tau)^2 = 0 ==> (d tau) = 0 ==> Delta tau = 0),   
   we also know that *a photon has no inertial rest frame* as that would   
   contradict the postulate of the constancy of c, one of two postulates which   
   make up the special principle of relativity which special relativity is   
   based on, *and* the Planck--Einstein relation E = p c = h f.   
      
   Curiously, special relativity fails to describe *completely* a motion at the   
   speed c that it is based on.
