Well, maybe we should be a bit more intellectual; you never know what the lurkers want to hear, since they don't speak up and tell us! So I'm just gonna throw this out there: supermassive black holes at the center of active galactic nuclei. While I think it is now clear that AGNs evidencing broad hydrogen lines and those lacking such spectral features differ only in the angle at which they're situated relative to our line of sight, due to interstellar dust thick enough to absorb the vast intensity of light put out by the central black hole's accretion disk, but it still seems unclear precisely what the structure of such AGNs within a parsec is, particularly whether or not the dust is in the shape of a torus or otherwise.

Even without the dust problem, most active galaxies are REAL far away, I dont' think we can see detailed structure of black hole discs, or ever will with telescopes. My guess is that "supermassive black holes" are actually the combined result of mutliple objects, perhaps thousands, interacting (even colliding) in the center. Come to think of it, black holes sort of defy logic and physics (requiring a singularity), and possibly don't exist at all, so we could be talking here about the supermassive easter bunny at the center of quasars.
