Can scientist undestand how galaxies work?

It sounds like they are slowly figuring out how galaxies operate.
I read this and feel I understand but, this is very complicated.
See link.

I hadn't heard the term circumgalactic medium and here it's what fuels galaxies, including ours.
Apparently they fuel galaxies' ability to form stars, and in turn the stars refuel the CGM. It's a cycle.
Very interesting.
I can't help but think that something is lost along the way, and that's why galaxies eventually lose their ability to form new stars. Essentially, dying.
With all the talk about Kepler and James Webb, I almost forgot about Hubble. Another success story out of NASA.
