Actively growing supermassive black holes in centers of galaxies are common even in cosmic voids, the most rarefied and empty regions of the universe. In a study of more than 1,000 void galaxies, using data from the Sloan Digital Sky Survey (SDSS-II), astronomers from Drexel and Widener Universities announced that the growth of these monster black holes -- with masses millions to hundreds of millions times that of our sun -- are found where galaxies are sparse and interact very little with each other. The researchers also found that the accretion of matter onto these void black holes is slower than in denser galactic environments.
