Which outcome occurs when gravity's field strength increases?

A)Photons lose energy, redshift increases.
B)Spacetime flattens; light travels faster.
C)Time accelerates; wavelengths blueshift.
D)Observed mass paradoxically decreases slightly.

💡 Explanation

Gravitational redshift occurs due to the equivalence principle; more energy is lost escaping the gravitational field. High gravity stretches spacetime, causing photons to lose energy via gravitational redshift because, rather than blueshift, energy is being expended working 'uphill'.
