Abstract

One proposed method to probe the existence of regular black holes is by overspinning them beyond their critical spin, as they are not constrained by the weak cosmic censorship conjecture. Several mechanisms have been suggested to achieve this, one of which involves sending a test particle to destroy the event horizon. In this study, we review the process of black hole destruction via test particles: its feasibility, necessary conditions, and the potential caveats involved. We also discuss key observables that could be detected by next-generation instruments, particularly the appearance of such objects when surrounded by an accretion disk, in both their final and transitional states. Finally, we highlight potential gaps and open questions in this area of research.
