Questions about time dilation and intense gravity of black holes

1. Is it true that an atomic clock will run faster at a higher altitude where gravity is weaker?

2. Would time slow down almost to a stop as one approaches infinitesimally close to a black hole event horizon?

3. If time slows down near a black hole, then from a vantage point very near a black hole event horizon wouldn't the rate of infalling matter increase, since the universe further away is not affected by time dilation?

4. At the event horizon, wouldn't all the matter in the whole universe get sucked into the black hole, and the size of the black hole expand to fill the universe, maybe become a new universe?

5. Wouldn't all the matter getting pulled into the event horizon be length contracted, and therefore accumulate into a thin massive shell as the whole shebang gained mass and the event horizon moved outwards?

6. Don't massive shells exert zero net gravitational force on objects inside them?

7. At the instant the event horizon is crossed, assuming one survived, wouldn't one then find oneself inside a large empty space?

8. Wouldn't Hawking radiation be emitted into this empty space?

9. Wouldn't radiation emitted by the event horizon be highly redshifted, since the event horizon increased in radius at such a huge rate?

10. Isn't a black hole a black body emitter?

11. Could this Hawking radiation be shifted into the microwave spectrum, if viewed from the inside?

12. Could we be inside a black hole now?

13. Could the cosmic microwave background be redshifted Hawking radiation, essentially an image of the inside of the event horizon?

14. Black holes begin as supernovae, with only 6-15 solar masses. Could Hawking radiation from accreted matter outside the black hole, have led to baryogenesis inside the black hole?

15. Could these questions form a more complete cosmological model?

16. Should I be nominated for a nobel prize? :-)
