Description
Consider, in the domain of wormhole, a point $p$ (observation event) and a timelike curve $\gamma$ (worldline of light source).
We prove that for infinitely many positive integers $\kappa$ there is a past-pointing lightlike geodesic $\lambda_{\kappa}$ of Morse index $\kappa$ from $p$ to $\gamma$ , hence an observer at $p$ sees infinitely many images of $\gamma$.
We will show that in the rotating traversable wormhole the occurrence of infinitely many images is intimately related to the occurrence of centrifugal-plus-Coriolis force reversal.
