If you want an honest answer, the answer is WE DO NOT KNOW. It could be, it could be not.
Look, just couple of weeks or months ago we find out that our Earth's core is significantly different than we previously thought.
We don't know how many ground water is on our planet. It may be surprising but we really don't know that. Here is more about the fact that we actually don't know how much ground water we have in lot of areas on our planet, more here from Jay Famiglietti from the University of California, Irvine (he speaks about that at about 43:45)
If we don't know these things that are macroscopic and relatively easy to observe and find out, then you have to admit that our knowledge about black holes, what is inside of black holes (we are not 100% sure what is inside of our own planet as I mentioned earlier; this information changes every few years or decades accourding to the new research and tests) and the origin of the Universe and Universes is in its infancy and we have a lot of research ahead. We are only in the beginning.
So, all we have right now is the observation of the effects of this "things" called black holes and a lot of mathematical formulas that could or could not be true.
So, in my opinion it's a good question, but unfortunately nobody can give a definitive answer, if he is honest, of course.
