摘 要: | It is measured by Wang et al. That a pulse advancement shift of 62(±1)ns gives from the shift an effective group velocity index of n g=-310(±5). A signal advancement shift was predicted by Einstein if the signal propagation could exceed the vacuum speed of light. But Einstein was negative for this possibility, and hence negative the possibility about greater than the vacuum speed of light. Therefore, Einsteins prediction was testified negatively by the experiment of Wang et al. If we use a new structure of the spacetime, the Finsler spacetime d s 4, then the spacelike and the timelike can be equivalent on the new structure.
