← ScienceWhich effect increases when a rapidly spinning black hole's event horizon shrinks?
A)Gravitational shear stress on infalling matter
B)Hawking radiation emission of virtual particles
C)Frame-dragging influence distorting spacetime✓
D)Lense-Thirring precession of orbital planes
💡 Explanation
Frame-dragging increases locally because the Kerr metric defines how the black hole's angular momentum distorts spacetime. This amplifies its effect dragging space around with it. Therefore, the frame-dragging increases, rather than altering shear stresses because matter distribution or radiation levels being influenced.
