#1. No. The light beam would be gobbled up by the black hole at the speed of light
(or at least going at that speed as measured by someone in the vicinity of the light ray/mw)
#2. Yes. Black holes have varying mass, hence, varying gravity.
This can be determined by observing the orbits of nearby stars surrounding
a black hole. This has been demonstrated by looking at our own black hole at the
center of the Milky Way. See
#3. No. That's just the way things are. The phenomenon
is called the Pauli Exclusion Principle. Physics, and life, would be completely different if the Pauli Principle were not true.
