← ScienceWhich distortion occurs to spacetime when a black hole evaporates?
A)Decreased curvature near event horizon✓
B)Increased cosmological constant expansion rate
C)Stable wormhole formation probability rises
D)Dark energy density locally increases
💡 Explanation
Hawking radiation causes black holes to lose mass; reducing event horizon size means gravity is now smaller, therefore spacetime curvature near the event horizon will weaken, rather than strengthen because more mass would lead to greater curvature.
