On the validity of Strong Cosmic Censorship Conjecture in presence of Dirac fields

Understand

A well posed theory of nature is expected to determine the future of an observer uniquely from a given set of appropriate initial data.

• In the context of general relativity, this is ensured by Penrose's strong cosmic censorship conjecture.
• But in recent years, several examples are found which suggest breakdown of the deterministic nature of the theory in Reissner-Nordstrom-de Sitter black holes under the influence of different fundamental fields.
• Nevertheless, the situation has been reassuring for the case of astrophysically meaningful Kerr-de Sitter black hole solutions which seems to respect the conjecture.
