空时空、广义相对论原理和协变以太理论
Empty space-time, general relativity principle and covariant ether theories
摘要：
我们从广义相对论原理出发，寻找空时空的性质。已经发现了无数的所谓协变以太理论（CET），它们和狭义相对论（SRT）一样，满足空时空物理学中所有已知的实验事实。在这方面，一个新的方法来测试SRT的实验问题进行了讨论。特别是，我们表明，协变以太理论预测的依赖性的绝对速度的观测的参考系的Wigner角。因此，这种依赖性的测量能够区分SRT和CET。证明了Lorentz以太理论是CET之一，对应于物理时空中容许的伽利略变换。因此，我们得出结论，SRT和洛伦兹以太理论可以区分实验，至少在原则上。提出了一个基于穆斯堡尔效应的关键实验。
英文摘要：
We look for the properties of empty space-time proceeding from the general relativity principle. An infinite number of the so-called covariant ether theories (CETs) has been found, which, like the special relativity theory (SRT), satisfy all known experimental facts in the physics of empty space-time. In this connection a new approach to the problem of experimental testing of SRT is discussed. In particular, we show that covariant ether theories predict a dependence of Thomas-Wigner angle on an absolute velocity of a reference frame of observation. Hence, a measurement of this dependence is capable to distinguish SRT and CETs. It has been shown that the Lorentz ether theory is one of CETs, corresponding to the admissible Galilean transformations in physical space-time. Hence, we conclude that SRT and Lorentz ether theory can be distinguished experimentally, at least in principle. A crucial experiments, based on the Moessbauer effect, has been proposed.
