← ScienceWhich consequence occurs when a celestial object's size decreases, exceeding its Schwarzschild radius?
A)Increased gravitational time dilation occurs✓
B)Hawking radiation emission ceases
C)Orbital velocity decay propagates outward
D)Event horizon surface tension increases
💡 Explanation
Gravitational collapse creates a black hole because extreme mass concentration causes spacetime curvature to increase dramatically near the object—this is gravitational time dilation. Therefore, time effectively stops at the event horizon rather than altering radiation or orbital mechanics.
