Spacetimes which have been considered counter-examples to strong cosmic censorship are revisited. We demonstrate the classical instability of the Cauchy horizon inside charged black holes embedded in de Sitter spacetime for all values of the physical parameters. The relevant modes which maintain the instability, in the regime which was previously considered stable, originate as outgoing modes near to the black hole event horizon. This same mechanism is also relevant for the instability of Cauchy horizons in other proposed counter-examples of strong cosmic censorship.

    gr-qc 2025-01 conditional novelty 4.0 of 10

    A WKB-based scan of quasinormal mode decay rates shows Strong Cosmic Censorship is violated in a region of the Reissner-Nordström de Sitter parameter space near extremality.
