Will our universe become a black hole?
Unlikely. Recent developments that show our universe is expanding at an ever-increasing rate. The cause of the expansion, called dark energy, is not understood, but it appears that the universe is destined to undergo a slow and cold death. If there were enough mass in the universe, and if dark energy did not exist, then it might have been possible for the universe to collapse in on itself, condensing all matter and energy to an almost infinitely small point, like a black hole.
