I'm trying to understand the Einstein field equations. My rough understanding is that the local curvature is due to the local stress-energy. Ok, a mass curves space...I get it. But, isn't space curved in the vacuum surrounding a mass? I mean, light is bent by a star even at some distance away from the star. Isn't the stress-energy zero outside the star?
Does this have something to do with the Weyl curvature which isn't included in the field equations?
