In the context of the news article below about NASA and a sky survey that they believe has identified all of the galaxies in about 400 million lightyears from us that have super-massive black holes in their center, how would some of these be inactive? Supposedly our own galaxy has an inactive blackhole. First, I know the idea of inactivity because all of the matter in the local space has been sucked out already, but we are talking galactic centers, the gravitational pivot on which the pinwheel (in our case) spins. So, how would something that is at the center of all that action, stars packed closer than icebergs on the north Atlantic, be inactive?
