← ScienceWhich consequence results when extremely high velocities approach a black hole's event horizon?
A)Gravitational blueshift of emitted light✓
B)Increased Hawking radiation emission
C)Spacetime curvature cancels momentum
D)Frame dragging halts object spin
💡 Explanation
Approaching a black hole causes a gravitational blueshift because the *gravitational redshift* observed by a distant observer becomes infinitely large. Therefore, emitted light becomes increasingly blue, rather than decreased redshift, due to curvature effects.
