非均匀真空：弯曲时空的一种新解释
Inhomogeneous Vacuum: An Alternative Interpretation of the Curved Space-time
发现了光在弯曲时空中传播与在渐变折射率介质中传播的惊人的相似性. 指出在光的传播中, 弯曲的时空等价于一个非均匀的真空. 导出了静态球对称引力场中这种非均匀真空的渐变折射率. 这一结果为天体物理学中的引力透镜问题提供了一种简单方便的分析方法.
he strong similarities between the light propagation in a curved space-time and that in a medium with graded refractive index are found. It is pointed out that a curved space-time is equivalent to an inhomogeneous vacuum for light propagation. The corresponding graded refractive index of the vacuum in a static spherically symmetrical gravitational field is derived. This result provides a simple and convenient way to analyze the gravitational lensing in astrophysics.
