Not a physicist but it seems to be part of astrophysics culture, and it's a good "base measure" for interstellar space (i.e., if something is < 1pc away it's likely within your same star system). A parsec is ~3.26 lys, for context.
- hnuser123456 2y agoAt the stellar density in our region of the galaxy, sure. The density is hundreds of times higher closer to the center.
- lou1306 2y agoYeah it is obviously informed by our local environment, the very definition of parsec is tied to the structure of our solar system.
