← ScienceWhich risk increases when black hole mass decreases?
A)Hawking radiation rate increases greatly✓
B)Event horizon radius increases slightly
C)Gravitational lensing effect diminishes steadily
D)Spacetime singularity weakens significantly
💡 Explanation
Decreasing black hole mass increases curvature gradient near its event horizon; because Hawking radiation involves quantum effects near intense spacetime curvature, its rate increases; therefore a microscopic black hole evaporates faster, rather than exhibiting a subtle change in size or gravitational effect.
