3. There is no speed of darkness. It is merely the absence of light.
4. This is an incredibly stupid question. Black boxes (which are painted orange for the most part) survive crashes because they're built incredibly densely. If a plane was built in the same way it wouldn't be able to move. And it wouldn't help the passengers either. Even if the plane stayed intact (and somehow managed to be in the air in the first place) in a crash, you'd get identical g-forces and so the passengers would still go splat.
12. Birds don't fall out of trees when they sleep because of the way their leg muscles are structured. When they relax (to go to sleep) their feet grip tighter. They have to make an effort to let go.
19. You can't travel at the speed of light. Ever.
