The edge of the universe is expanding at the speed of light, and has been doing so for quite some time. The matter nearer to the edge thereof, though not moving quite that fast, is still moving at relativistic speeds. Black holes simply move too slow to reach the matter nearer to the edge of the universe. Therefore, in the extremely distant future(barring any extra-universal events), the edge of the universe will likely be the safest place to live--if we can just get there!
