← ScienceWhich consequence results when light bends passing a celestial body?
A)Time delay for distant signals✓
B)Gravitational blueshift increases sharply
C)Spacecraft velocity remains constant, locally
D)Observed parallax remains nearly constant
💡 Explanation
Gravitational time dilation occurs because spacetime is curved by mass. Time slows near the massive object, leading to the Shapiro delay mechanism. Therefore, signals experience a time delay rather than changes in frequency (blueshift), because relative velocity remains sub-luminal.
