这个我还真不是特别清楚。狭义相对论的确讨论过时空一体的问题。不过不记得有过这种定量关系的表述。 ...

遵照TAINS的嘱咐,我特别的刀百度上将狭义相对论搜了一下并读了一遍。
可以肯定的说:在百度百科这个水平上 ...
At the time, it was known that Maxwell's equations, when applied to moving bodies, led to asymmetries (Moving magnet and conductor problem), and that it had not been possible to discover any motion of the Earth relative to the 'light medium'. Einstein puts forward two postulates to explain these observations. First, he applies the principle of relativity, which states that the laws of physics remain the same for any non-accelerating frame of reference (called an inertial reference frame), to the laws of electrodynamics and optics as well as mechanics. In the second postulate, Einstein proposes that the speed of light has the same value in all inertial frames of reference, independent of the state of motion of the emitting body.
