KnowraGravitational redshiftLinked fromLinked fromThe 21 pages that link to Gravitational redshift, each with the reason it gives.All 21Broader topic 1Related 11Compared with 9Doppler effectCompared with: It shifts light without requiring relative motion between source and observer.Gravitational lensingCompared with: Both arise in curved spacetime, but redshift changes frequency rather than image geometry.Cosmological redshiftCompared with: It shifts light through gravity rather than the universe’s changing scale.Weak gravitational lensingCompared with: It is another gravitational effect on light, but not the image-shape distortion measured here.Gravitational lensCompared with: Gravity can alter light’s energy as well as its path, producing a distinct observable effect.Radial velocityCompared with: It can shift spectral lines even when no radial motion causes the shift.Relativistic Doppler effectCompared with: It shifts frequency through gravity rather than the relative motion central to this effect.Shapiro time delayCompared with: It changes measured frequency, whereas the Shapiro effect concerns signal travel time.Tired lightCompared with: It is a confirmed energy-change mechanism, but does not account for the general distance–redshift relation.
