Not really.

2) Where does matter falling into a black hole go ?
Into the hole. Just like with any other hole, really.

3) As the Universe expands and cools, will we see everything cooling so much it gets denser ?
No.

4) Do you have a nice graph showing how the Universe size varies over time ?
No, but I know some people who do.

5) Is NASA suppressing technologies better than rockets ?
No.

6) What's the best way to go high enough to see the curve of the Earth ?
A rocket.
