← ScienceWhich effect inevitably follows accelerating a black box indefinitely, because kinetic energy relates directly to observed mass?
A)Spacetime curvature increases linearly
B)Doppler effect plateaus indefinitely
C)Hawking radiation emission concentrates
D)Event horizon area expands exponentially✓
💡 Explanation
The event horizon expands because the mass-energy equivalence principle dictates added kinetic energy must gravitationally increase the black box's mass, expanding a larger event horizon; therefore, alternative effects saturate and horizon growth outpaces other conditions rather than linearly.
