You’re always moving because the earth is always rotating. It’s also revolving around the sun, making a complete orbit once a year. Our sun, likewise, revolves around the Milky Way galaxy, taking our entire solar system with it. It takes the sun approximately 225-250 million years to make a full trip around the galaxy, a period known as a “cosmic year.” This means that at any given moment, our planet is in roughly the same spot in the Milky Way it was 250 million years ago. Today, that point in history coincides with the Permian-Triassic extinction, the most catastrophic of our planet’s five mass extinction events, when 90% of marine species and 70% of land species died out. After the extensive decimation, the Triassic period began, bringing with it Archosaurs, early grasshoppers, and eventually the first mammals, all of which lived on the supercontinent known as Pangaea. In another 250 million years, we’ll arrive back at this spot in the Milky Way.
