The interior of black holes offers a unique window into extreme gravity. I will present two recent studies revealing novel structures near singularities. First, in Einstein–Maxwell–scalar theory, spontaneously scalarized black holes lack a smooth inner horizon; instead, the interior collapses into a Kasner singularity with a universal scaling relation. Second, with higher-curvature corrections, we identify three distinct near-singularity regimes: modified Kasner eons, persistent oscillations, and growing spikes—all beyond classical predictions. These findings uncover unexpected order and universality inside black holes, offering fresh insights into spacetime singularities and quantum gravity.
