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.

Explanation:
Spectroscopy is a technique in science that allows us to study the interaction of light with matter. It involves the analysis of the different wavelengths of light emitted, absorbed, or scattered by a substance. In the context of the Big Bang theory, spectroscopy provides evidence through the observation of red shifts in the light emitted by distant galaxies.
Red shift refers to the phenomenon where the wavelength of light is stretched, causing it to shift towards longer wavelengths, towards the red end of the electromagnetic spectrum. This can occur when an object, such as a galaxy, is moving away from us.
The Big Bang theory proposes that the universe originated from a single point and has been expanding ever since. According to this theory, galaxies are moving away from each other as the universe continues to expand. Spectroscopy allows scientists to measure the redshift of light from distant galaxies. By observing the redshift, they can determine the velocity at which these galaxies are moving away from us.
The red shift observed in the light from distant galaxies supports the idea of an expanding universe and is consistent with the predictions of the Big Bang theory. The further apart the galaxies are, the greater the redshift observed, indicating that they are moving away at faster velocities. This observation aligns with the concept that the universe originated from a single point and has been expanding over time.
Therefore, spectroscopy, specifically the observation of red shifts in the light emitted from galaxies, provides evidence for the Big Bang theory by confirming the notion of an expanding universe.
