I myself have thought about it constantly since an incredible analogy was first put out there several years ago; namely, that spacetime itself flows into black holes. And once it reaches the event horizon, it is flowing inward faster than the speed of light. That's why even light can't escape: the space in which it is embedded is flowing inward faster than c, while the best it can do is c outward. So it is carried in. Note this was only supposed to be an analogy to help you understand! Now it appears it may be something more than that.
Why not.
