According to the norm of identifying truth in this theory, and Newton's first law which is a basis that can look at the overall situation. By virtue of the electron storage ring as an experimental fact, it is pointed out: Only in reality can there be inertia, and vice versa. Inertia represents the continuity of the development of thing. As the speed gradually approaches to the c, the particle's mass also approaches to zero along with its static mass, which is the energy shrinkage effect of high-speed particles, and also the primary factor causing the spectrum redshift. Therefore, the Big Bang theory is wrong. All photons are produced from the high-density particles through electromagnetic radiations. Wherever there is fluctuation, there must be mass, and vice versa. This is the correct understanding of "wave-particle duality". No matter the high-speed electrons or the photons produced by them all have different static masses, but their charge-mass ratio is always the same physical constant, and not affected by relativistic effects and electromagnetic radiations. Which constitutes the internal mechanism of the uncertainty principle and conforms to the experimental facts related to it. It can be proved that in a constant magnetic field, the high-speed electron or photon with a relatively large curvature radius, which has a high moving speed and less mass, energy and wave frequency. Since Einstein used the absolute space-time established by Newton as the criterion and came to the conclusion that relative space-time was curved, then he should no longer make circular arguments, that was, used the relative space-time as the criterion, to change the unit length and time established by the absolute space-time.
