Beyond the Horizon: Can Spinning Gyroscopes Reveal Naked Singularities?
![Within the ergoregion of a rotating Kerr-Newman black hole, orbital velocity Ω diverges near the central region for naked singularities, distinctly differentiating their behavior from that of a black hole where Ω remains finite, a phenomenon observable across varying [latex] Q [/latex] values and measured in units of [latex] M^{-1} [/latex] as a function of radial coordinate [latex] r [/latex] in units of [latex] M [/latex].](https://arxiv.org/html/2602.18972v1/x6.png)
