The red shift in atomic spectra of distance cosmic objects is a source of evidence for the big bang theory. The red shift, the expanded wavelength of light due to the Doppler Effect of faraway objects, suggests that these objects are moving away from earth. This is a phenomenon predicted by the Big Bang Theory.
