A grave conflicting aspect is uncovered for the conventional wisdom in relativity theory regarding spacetime units. No account has ever been taken of the undeniable fact that these units are contingent on nature, resulting in the present convention in which the same spacetime units are used in all reference frames. This convention runs counter to Einstein's denunciation of an absolute space and an absolute time propounded by Newton. This conflict can be resolved only by our recent proposal [Phys. Essays 11, 521 (1998); 12, 368 (1999)] for introducing separate spacetime units for each reference frame.
