Most of the space in the universe is empty. Part of the reason for the emptiness of space is that the matter in the universe is gravitationally attracted to other pieces of matter. Most matter in the universe gets pulled into one of the many massive systems held together by the gravitational pull of black holes. These massive systems can be millions of light-years wide and contain millions of stars and planets.
What do scientists call these massive systems?
