The garbage dump galaxy was a standard single galaxy consisting of an F-type star and six barren planets.
Like most galaxies in the Milky Way, this place was ordinary. Although it should not be reduced to a place where garbage was piled, there was no garbage dump in the Milky Way. Many people threw garbage here, so it became a garbage dump galaxy.
How to carry out recycling was something that interstellar civilizations had to consider. Civilizations with the ability would naturally be able to deal with the large amount of waste produced by the rapid development of those civilizations.
However, for many civilizations that had just come into contact with the galaxy or did not rely on their strength to fly, dealing with the garbage they produced was a thankless task.
However, the Milky Way was so vast. Even if one threw the trash away, no one would care, right?
