    Note that it makes a lot of assumptions beyond the stated ones, such as: * the only objects in space are stars * all stars are equally bright * the average brightness is one that can be seen (unless you roll all this into "homogeneous"?)

      Yeah I'm confused because couldn't a black hole between us and a star be the reason for a black spot? That times a bajillion for whatever else is out there.

        gravitational lensing would make the light go around the black hole.
