The correct response is: The intensities of peaks show that galaxies are moving away from each other.
Spectroscopy is the study of the interaction of light with matter. When light from distant galaxies is observed using spectroscopy, the wavelengths of the light can be measured. The wavelengths of light emitted by objects moving away from us are stretched, causing them to shift towards the red end of the spectrum. This phenomenon is known as redshift. By analyzing the redshift of light from distant galaxies, scientists have found that the majority of galaxies in the universe are moving away from each other. This observation supports the concept of an expanding universe, which is a fundamental aspect of the Big Bang theory.
