← ScienceWhich consequence results when a gyroscope's extreme mass approaches a black hole's event horizon?
A)Frame dragging causes axis precession✓
B)Sagnac effect cancels rotation
C)Gyroscopic lock prevents fall
D)Conservation overwhelms tidal forces
💡 Explanation
Frame dragging causes axis precession because spacetime curvature induced by the black hole's mass twists space around it; therefore, the gyroscope precesses rather than maintaining its orientation perfectly because of the rotation of this curved spacetime.
