Ok, so how does that apply? Will a black hole which is not surrounded by a cloud of matter -- one which has pulled all the available matter into its event horizon -- will such an object present as a source of gravity?

Let me think about that a bit. All right, I have to confess I have always thought of a black hole as looking something like a bowling ball. Thinking about it, I realize that the black hole would normally form, leaving a great deal of matter still outside it. My bowling ball becomes a storm...

Again, if the collapsing matter remains the cause of the spatial curvature, how can the matter inside the event horizon have that (or any other) effect outside that horizon? How can gravitons from inside escape? Or must I believe that gravity is not quantized?

Yes, I saw that in one of the other threads. But I don't understand it. How does the spacetime curvature maintain itself once the gravity that caused it becomes unavailable? If I moved the black hole somewhere else, would the curved spacetime just remain where it was, causeless?

If: Gravity propagates via "particles" of gravity, and The particles of gravity are massless and so move at the speed of light then how can the gravity particles escape from a black hole? Aren't they as trapped as the photons? It seems as if black holes should present no gravitational field...

Thank you all for your various answers. I'm trying to gain some intuitive understanding of quantum behaviour, despite having been told that this is a perfectly useless endeavor.

So my next question would have been, well why do I hear of subatomic particles "vibrating" or having a certain "frequency", but I've just been off looking that up, and what I seem to see is, no, there is no actual motion, there is a static state which happens to be best described by the...

Electrons rotate around a nucleus for long periods of time. Where does the energy for this motion come from? Ok, I realize that electrons don't actually rotate around the nucleus, like a tiny solar system. But if the electron is wave function, it's still constantly vibrating, constant...
