基于量纲分析从物理和数学角度推导光速原理

Derivation of the Principle of Light Speed from Physical and Mathematical Perspectives Based on Dimensional Analysis

介绍了量纲关系“能量 ≡ 质量×(速度)2”的推导过程,讨论了质量体的概念。分别从物理和数学角度推导了光速原理,即宇宙总能量和宇宙总质量比值的平方根等于光速。光子是以光速运动的质量体。讨论了引力对于光速的影响。在没有引力或者引力作用的影响可以忽略的条件下光速不变。

The deduction process of dimensional relation of“energy≡mass×(speed)2”is introduced.The concept of mass body is discussed.The principle of light speed is deduced respectively from the physical and mathematical point of view,that is,the square root of the ratio of the total universal energy to the total universal mass equals light speed.Photons are mass bodies moving at light speed.The effect of gravitation on light speed is discussed.The light speed remains unchanged in cases where there is no gravitation or the effects of gravitation are negligible.
