Paul, trying to discuss ten questions in a single thread is a surefire route to confusion and madness. Questions on different subjects should be in different threads.
Also, most of these questions really belong in other forums than this one (Quantum Physics), IMO. I suggest:
1, 3, 4, 5, 6: Astrophysics
7: Beyond the Standard Model
8: Relativity or Quantum Physics
10: Classical Physics or maybe Philosophy
