Impact of curvature divergences on physical observers in a wormhole space-time with horizons

Understand

The impact of curvature divergences on physical observers in a black hole space-time which, nonetheless, is geodesically complete is investigated.

• This space-time is an exact solution of certain extensions of General Relativity coupled to Maxwell's electrodynamics and, roughly speaking, consists on two Reissner-Nordstr\"{o}m (or Schwarzschild or Minkowski) geometries connected by a spherical wormhole near the center.
• We find that, despite the existence of infinite tidal forces, causal contact is never lost among the elements making up the observer.
• This suggests that curvature divergences may not be as pathological as traditionally thought.
