Quizplus · Accepted Answer

Galaxies recycle material from one generation of stars to the next, and without this recycling we could not exist. This process allows for the creation of new stars, planets, and ultimately life. Additionally, galaxies provide the gravitational forces necessary to keep our own solar system stable and our planet in orbit around the sun.
