Space is fake and gay, but I haven't come up with a plausible explanation for stars. Perhaps they are more directional with their light output? Either way they are not effective at lighting anything, they're just dim dots in the night sky. I do think the moon is likely a reflection of the sun on the firmament; that's the only thing that makes sense with how the moon follows the sun and how we only see one side of it. I think there is a lot that we are not privy to that will explain the stars better, like maybe we live in a tiny containment prison of the actual world.
