Why? At a distance, gravity doesn't really care about density, only mass. An infinitely dense object would shred anything it touches by its infinitely high tidal force, but there's only a limited amount of material it can touch within a given time and the Universe is not infinitely old. |

Okay, to be precise something like that can't have existed in the observable universe (at the time we observe), but could exist in a distant bubble that's expanding at the speed of light.
