Do black holes pull in and keep spacetime itself or merely warp it but ultimately let it pass through? Forgive my 'amazing' MS-Paint skills, but this is along the lines of what i'm wondering:



Is there any situation where Scenario A occurs, or is space always dragged back out as in Scenario B?
Black holes orbit things and galaxies move within space, so it would be safe to assume that black holes move through space-time and do not hold it in any particular state or position. They simply drag their "depression" along with them as they go.
