← ScienceWhich consequence results when spacecraft experience extreme spacetime curvature?
A)Communication blackout with ground stations✓
B)Propellant efficiency spontaneously increases
C)Altered rate of radioactive decay
D)Hull experiences increased structural redshifting
💡 Explanation
The extreme spacetime curvature of a black hole event horizon affecting radio waves leads to gravitational lensing and signal distortion, hence, Communication blackout occurs because increased curvature scatters the signal path, rather than redshifting because the frequency shift is due to relative motion.
