: : What happens when a black hole gains too much mass and has too much gravity?

: There is no theoretical limit on the mass of a black hole.

If there is no theoretical limit, what happens to them in the Big Crunch? One step more, would not the Big Crunch be a black hole of some type at max mass? Hence no Big Bang?? I believe that there is a life cycle to all things. There must be an end to black holes or a next step in its life cycle that we have not yet observed do to technology or the age of the universe is too young for the next step.
