However, the Heat Death hypothesis does allow for a large portion of the matter in the universe eventually falling into multiple black holes, and for black holes merging to form more massive black holes, possibly massing many times the Galaxy's central black hole.
It is impossible to estimate how many people exist in the universe since we have no way of knowing how many worlds have life and how many of those have produced life forms that might be called people.
