一、检测光子静质量的意义 首先,这对狭义相对论是一个很好的检验。我们知道,比起“惯性系地位等价”来说,“光速不变原理”在狭义相对论的理论基础中显得有些突兀,好像是爱因斯坦(Einstein)为使麦克斯韦(Maxwell)方程满足洛仑兹(Lorentz)协变而直接塞入的。不过非常凑巧的是,麦克斯韦电磁场方程刚好能够预言所有的电磁辐射在真空中都以相同的速度c传播,且与其频率无关。 First, the significance of detecting photon static quality First of all, this is a very good test of special theory of relativity. We know that the “principle of invariance of light velocity” is somewhat abrupt in the theoretical foundations of special relativity, as opposed to “the equivalent of inertial system,” as if Einstein had made the Maxwell equation satisfy Lorentz Lorentz co-opted directly into it. However, it is very coincidental that the Maxwell’s electromagnetic field equation just predicts that all the electromagnetic radiation propagates in the vacuum at the same velocity c regardless of its frequency.
