Which phenomenon significantly redshifts light from distant galaxies because of spacetime?

💡 Explanation

Cosmological redshift stretches photons wavelengths because expansion itself alters spacetime, therefore increasing observed wavelength rather than just Doppler shift from movement, which is present, or gravitational effects concentrated near massive objects.
