I think the black hole converts matter into dark energy. It spits out matter in the form of dark energy (or dark matter). This is why scientists are astonished about why the expansion on the universe is speeding up. Its because of this dark energy pushing the large amounts of ordinary mass. The more ordinary mass the black holes gobble up, the faster the expansion of the universe.
Just My Theory..
