Empirical exploration of timelike geodesics around a rotating wormhole.

Fanny-Leicht Gymnasium Stuttgart, Fanny-Leicht Str. 13, 70563 Stuttgart-Vaihingen, Germany In an advanced course on general relativity, some exotic spacetimes like wormholes with a more complex topology than the standard Schwarzschild spacetime can be studied in detail. In this regard, it has been pointed out by Morris and Thorne that wormholes could be a valuable tool for teaching general relativity. In this paper, we claim rotating wormholes might also have a pedagogical role in general relativity, and present an empirical approach to explore periodic orbits of such, that could be applied also to other spacetimes.
