  For *any* mass density D > 0, no matter how small, there is a mass M such that the object with that mass and density in volume V=M/D is a black hole. So it is also about how much stuff an object has, not just how much it's been smooshed.

  In thought, Black Holes are nothing more than a rotational atom smasher with one sole purpose and that is to break down matter into it's most fundamental particles.
