What is the red shift theory?

Answer 1

Shift in spectral lines indicates expanding Universe.

The Doppler shift, which is a change in spectral lines toward the red end of the spectrum, supports Edwin Hubble's theory of an expanding universe and has an impact on our current understanding of the Universe.

One important piece of evidence supporting the expanding universe model and the Big Bang theory is the phenomenon known as the "shifting of light" toward longer (redder) wavelengths as distant objects in the universe move away from us. This phenomenon is explained by the redshift theory, also called the Doppler effect.
