Possible Process of Photon Scattering in the Universe to Form Hubble Redshift

When visible light passes by the sun, it will form a bend. There are many stars like the sun in the universe. The light emitted by long-distance luminous planets spreads to the earth from the gaps between these planets, and will form a bend by the influence of stars along the light. According to the law of conservation of momentum, the slight bend of light will form a redshift, which can be derived from the redshift formula that forms the redshift formed by the long-distance propagation of light is proportional to the propagation distance. It can be predicted that lens galaxies will have obvious non-distance redshifts.
