Answer to Question 1

If we are at the center of the universe that contradicts the cosmological principle which says that no point is in any way different from any other point. It is not that everything is moving away from us per sec, it is that everything is moving away from everything else. No matter where we might be, we would observe that everything moved away from us.

Answer to Question 2

A more massive star collapses to a black hole in a hypernova, with bi-polar jets of gamma rays. In a less massive type II event, only a neutron star is left.
