摘要： The Einstein’s theory of special relativity is based on his two postulates. The first is that the laws of physics are the same in all inertial reference frames. The second is that the velocity of light in the vacuum is the same in all inertial frames. The theory of special relativity is considered to be supported by a large number of experiments. This paper revisits the two postulates according to the new interpretations to the exact solutions of moving sources in the laboratory frame. The exact solutions are obtained using the classic Maxwell’s theory, which clearly show that the propagation velocity of the electromagnetic waves of moving sources in the vacuum is not isotropic; the propagation velocity of the electromagnetic waves and the moving velocity of the sources cannot be added like vectors; the transverse Doppler effect is intrinsically included in the fields of the moving sources. The electromagnetic sources are subject to the Newtonian mechanics, while the electromagnetic fields are subject to the Maxwell’s theory. We argue that since their behaviors are quite different, it is not a best choice to try to bind them together and force them to undergo the same coordinate transformations as a whole, like that in the Lorentz transformations. Furthermore, the Maxwell’s theory does not impose any limitations on the velocity of the electromagnetic waves. To assume that all objects cannot move faster than the light in the vacuum need more examinations. We have carefully checked the main experiment results that were considered as supporting the special relativity. Unfortunately, we found that the experimental results may have been misinterpreted. We here propose a Galilean-Newtonian-Maxwellian relativity, which can give the same or even better explanations to those experimental results.

摘要：
It is reported that the Large High Altitude Air Shower Observatory (LHAASO) observed thousands 9 of very-high-energy photons up to ∼18 TeV from GRB 221009A. We study the survival rate of these 10 photons by considering the fact that they are absorbed by the extragalactic background light. By performing a set of 10 11 6 Monte-Carlo simulations, we explore the parameter space allowed by current 12 observations and find that the probability of predicting that LHAASO observes at least one photons 13 of 18 TeV from GRB 221009A within 2000 seconds is 4–5%. Hence, it is still possible for the standard 14 physics to interpret LHAASO’s observation in the energy range of several TeV. Our method can be 15 straightforwardly generalized to study more data sets of LHAASO and other experiments in the future.

摘要： 洛伦兹变换的时间膨胀是真实的物理效应还仅是数学的等效关系？本文提出一种独立实验方案，可在实验室坐标系比较和鉴别狭义相对论与 Lienard-Wiechert 推迟电磁场理论的物理真实性。 令一个高速运动电荷先后穿越两个相邻的皆配置有电场仪的屏蔽室；一方面可根据两种时空观分别计算出‘运动电荷的位置随时间变化’的理论曲线；另一方面可根据电场仪记录准确判断‘电荷位于第一个屏蔽室或第二个屏蔽室的时段’。将关于电荷位置的两条理论曲线与电场仪记录的实验曲线比较，即可判定何种理论符合自然实际。
