In this talk we analyze the effect of recently proposed classes of sudden future singularities on causal geodesics of FLRW spacetimes. Geodesics are shown to be extendible and just the equations for geodesic deviation are singular, although tidal forces are not strong enough to produce a Big Rip.

  1. Gauss-Bonnet Gravity and Spacetime Singularities

    gr-qc 2026-02 reject novelty 4.0

    The paper argues that Gauss-Bonnet terms weaken the FLRW singularity to a sudden, traversable one and make radial black-hole geodesics only weakly singular, but internal sign and branch errors undermine both arguments.
