Where did you hear this? I've never head of this...and no, it's not possible, it would have been detected if it was there.
nnouncing the discovery of three black holes in three normal galaxies, astronomers suggest that nearly all galaxies may harbor super-massive black holes that once powered quasars

Black holes do indeed suck you up for all practical purposes, a blackhole close enough to the sun would start feeding on the sun until it swallowed the entire sun. Even if it was not close enough to feed we would likely be able to detect the effects it would have on bodies like the sun.

EDIT: Geophysicists are speculating that at the very center of the Earth and other planets may have densities approaching that of black holes
At the core-mantle boundary, composition changes again. Seismic waves suggest this material is of a very high density (10-13 g/cm3), which can only correspond to a composition of metals rather than rock.www.visionlearning.com...
