Abstract

We make some considerations regarding the time delay of two light signals around a closed line, the well-known Sagnac effect. In our opinion, this experiment in flat space-time is simply a further test of Einstein’s equivalence principle. The revolving observer is physically equivalent to an observer at rest in a Lense-Thirring-like geometry.

围绕旋转和非旋转质量的圆形时间延迟

我们对两个光信号绕一条闭合线的时间延迟，即众所周知的萨格纳克效应作了一些考虑。在我们看来，这个在平坦时空中的实验只是对爱因斯坦等效原理的进一步检验。旋转的观测者在物理上相当于一个静止的观测者，在透镜-蒂林几何中。

期刊介绍： Gravitation and Cosmology is a peer-reviewed periodical, dealing with the full range of topics of gravitational physics and relativistic cosmology and published under the auspices of the Russian Gravitation Society and Peoplesâ€™ Friendship University of Russia. The journal publishes research papers, review articles and brief communications on the following fields: theoretical (classical and quantum) gravitation; relativistic astrophysics and cosmology, exact solutions and modern mathematical methods in gravitation and cosmology, including Lie groups, geometry and topology; unification theories including gravitation; fundamental physical constants and their possible variations; fundamental gravity experiments on Earth and in space; related topics. It also publishes selected old papers which have not lost their topicality but were previously published only in Russian and were not available to the worldwide research community
