Scientists' evidence for an expanding universe is called a because the light waves emitted by stars and galaxies are shifting toward the end of the visible color spectrum.

the answer is "scientists' evidence for an expanding universe is called a (blueshift, yellowshift, redshift, greenshift) because the light waves emitted by stars and galaxies are shifting toward the (yellow, blue, green, red) end of the visible color spectrum." the explanation behind this is that when an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer. if an object moves closer, the light moves to the blue end of the spectrum, as its wavelengths get shorter.
