A major piece of evidence supporting the big bang theory is faraway galaxies' stars' electromagnetic radiation reveals a change known as a "redshift," which makes the wavelengths look longer than they actually need to be.

Evidence of the universe's expansion comes from the Doppler redshift of light from far-off stars and galaxies (moving away from a central point). This makes the Big Bang Theory possible because, after the first "bang," all of the matter goes away from its origin.

The only procedure that we are aware of that can lengthen wavelengths occurs when the wave's origin is moving away from the observer. Therefore, we think that this is what is causing all of the radiation from far away. Extended wavelengths of galaxies, bring us to the idea that the universe is expanding.
