← ScienceWhich consequence results when near a black hole, a hypothetical, perfectly rigid rod extends beyond its tidal radius?
A)Length contraction resists radial stretching
B)Spacetime curvature causes differential stress✓
C)Mass increase prevents rod breakage
D)Hawking radiation stabilizes spacetime gradient
💡 Explanation
Spacetime curvature induces differential stress because gravity's pull varies along the rod, creating internal tension resulting in spaghettification. Therefore differential stress occurs, rather than length contraction perfectly opposing the force or radiation effects affecting rod stability.
