let me try these in a sensible manner with sensible answers
to your three questions.
1.) How does gravity get out of a black hole.
that's pretty much a stupid question but as usual coming from
a believer in QM its the norm.
answer: it was always there because of the mass that accumulated inside the center of the galaxy , it hasn't left
its there because of the mass inside the black hole.
2.) Why is the speed of gravity restricted to the speed of light
the bounds of a gravity field is restricted only to
the mass that causes the gravity field.
3.) What is opposing the black hole so that the black hole gravity does not go to infinity (What limits the collapse).
there is a constant collapse inside a black hole as long
as the black hole is feeding.
the gravity and pressures inside a black hole squeeze
the atoms inside it together so much that the electrons in
the atoms collapse inwards and these collapses cause energy
to be released from the atoms and this energy builds
up inside the mass until the energy can escape the gravity
of the mass.
light cannot escape the gravity because light has mass.
the excess energy escapes via gamma ray burst.
