Gravitational lensing caused by the gravitational field of massive objects has been studied and acknowledged for a long period of time. In this paper, however, we propose a different mechanism where the bending of light stems from the non-linear interaction of gravitational, electromagnetic and axion waves that creates the high curvature zone in the space-time fabric. The striking distinction in the present study is that in contrast to the convex lensing in the gravitational field of a massive object, hyperbolic nature of the high curvature zone of the background space-time may give rise to concave lensing. Expectedly detection of this kind of lensing becomes possible through satellite detectors.

旋转和扭曲宇宙中的引力透镜


由大质量物体的引力场引起的引力透镜效应已经被研究和认识了很长一段时间。然而，在本文中，我们提出了一种不同的机制，其中光的弯曲源于引力波、电磁波和轴子波的非线性相互作用，这种相互作用在时空结构中产生了高曲率区域。本研究的显着区别在于，与大质量物体引力场中的凸透镜相比，背景时空高曲率区域的双曲性质可能会产生凹透镜。预计通过卫星探测器可以探测到这种透镜效应。
