I can say this, since there is no end point in the universe there is no point of return, even for light. Light is traveling every time to reach the end.

A black hole does have boundaries. What exist outside the boundaries of a black hole is the known universe. What is inside the black hole can only be imagined. The universe has boundaries, but we have no clue as to the properties, if any outside these boundaries. We do not know if it conforms to the laws of physics that define our universe. Black holes are a part of our universe. What. if anything, is outside the universe is yet to be defined.

I suppose not.
You can't say that there's no end point, its just that "we" are not yet successful in finding it out. As for the light you say, did you ever chase it to find that it has reached an end or not?
Moreover, according to the laws of physics, a Black hole goe on contacting under its own gravity.But th esame laws say that our Universe is going on expanding.
So, next time you tink of the universe as a Black hole try & consider all the facts.

No.
A black hole is a very specific geometry of space time called a Schwarzchild metric. The universe as a whole does not have this metric.
