Null Geodesics and Gravitational Lensing in a Nonsingular Spacetime
The null geodesics and gravitational lensing in a nonsingular spacetime are investigated.According to the nature of the null geodesics, the spacetime is divided into several cases.In the weak deflection limit, we find the influence of the nonsingularity parameter q on the positions 7.5ft heavy duty gold metal round wedding arch photo backdrop stand
