Star 1 is a nearby star and star 2 is a similar type star much further away from Earth. When comparing the spectra, the lines in the spectra for star 2 are closer to the red end of the light spectrum. This is called red shift.
From this type of information, scientist believe that most stars in the universe are moving away from each other and from the Earth. How can redshift be used as evidence to support the Big Bang theory?
