当下的物理学家怎么了?超光速是产生γ射线主要原因,不是说γ射线本身能够加速到光速,而是产生机制是something's reached the limit of velocity, light speed, e.g. the veolocity of electron and positron absolutely reached to the limit at their shaking hands for annihilation accordingly. Peace & blessings to you, Mr 周 and all Chinese physicists. Paul Dirac said: Physicists are inclined to believe that an infinite field of any kind can never occur in nature. Nature always seems to deal only with finite quantities and that must mean either that the charge on the electron is not concentrated at a point or else there is some failure in the Coulomb law at very small distances. People have tried to set up theories of the electron for which the charge is not concentrated at a point.
