← ScienceWhich outcome results when strong gravitational fields alter spacetime?
A)Light redshifts; spectral lines shift proportionally✓
B)Molecular bonds strengthen dramatically everywhere
C)Objects gain measurable electric static charge
D)Inertial mass exponentially decreases rapidly
💡 Explanation
Gravitational redshift occurs because the equivalence principle dictates that gravity and acceleration are indistinguishable; therefore as light climbs out of a gravitational well it loses energy, thus stretching its wavelength and inducing a redshift, rather than molecular changes or generating unexpected electric charges.
