WHAT THE FUCK DOES THIS HAVE TO DO WITH ASTRONOMY?

Absorption and emission lines are pretty important in astronomy. As a simple example, you can see how much they're redshifted or blueshifted to tell how fast a star is moving away from or toward you.

only certain wavelengths of light are emitted from the atom, and for each atom the spectra are different. by observing the wavelengths emitted you can tell what element you're looking at, pretty important for determining the composition of celestial bodies when you can't just reach out and grab them.

everything. if you want to understand the stars you need to understand light. There's more to it than meets the eye ;)

You know, it may have helped if they mentioned the word "light" at any point.

Photons are "light"
Did you not take highschool physics?
