Exactly...I too believe what u have told is exactly right...It may be true that universe is expanding and so the black-hole may not be able to influence its gravitational force through such long distances relatively. But the unanswered question is how long does the universe expand? If one is to...

why can't a black-hole absorb its own black body radiation? (Black body radiation is also and electro magnetic field like light and so a black-hole with its intense gravitational field is expected not to emit even blackbody radiation also!)
