If at the beginning of the universe we had a singularity does that mean that every black hole has the potential to create a universe as we know it?
No. A singularity is really more a mathematical concept than a physical entity. It's true that the math describing both black holes and the Big Bang contain singularities, but they are not related. Also, a black hole only a mass a few times the mass of our Sun, or in the case of the those at the centers of galaxies, a couple million Suns. The Universe is obviously quite a lot more massive.
