← ScienceWhich risk increases when an interstellar spacecraft approaches event horizon?
A)Extreme tidal forces distort spacecraft✓
B)Reduced engine efficiency lowers thrust
C)Communications bandwidth with Earth drops
D)Radiation shielding unexpectedly exceeds limits
💡 Explanation
Tidal forces increase near a black hole because differential spacetime curvature creates extreme gravity gradients. This causes spaghettification, therefore structural integrity faces critical failure, rather than signal loss, because communications are directionally based.
