The Spacetime Ledger: Where Black Hole Spin Actually Goes

The provided text introduces the K-Limit framework, a theoretical model where gravitational collapse is halted by QCD chiral transitions to create a dense core rather than a singularity. This model explains the extremal spin limit of black holes as a self-regulating physical process rather than an arbitrary mathematical bound. By dividing a black hole's total angular momentum into matter rotation and geometric frame-dragging, the researcher demonstrates that as spin increases, the spacetime geometry absorbs a larger share of the energy. At the theoretical maximum, the geometry captures all incoming angular momentum, effectively choking off further growth through a dynamical saturation mechanism. This perspective suggests that cosmic censorship is a natural consequence of how rotating space interacts with matter. Ultimately, the paper aligns these findings with observational data from gravitational waves, showing that these objects appear identical to standard Kerr black holes despite their unique internal structures.
