Some of the Super-massive Black Holes don’t have any material nearby to eat. But others have a buffet table of cosmic goodies within reach. The Super-massive Black Holes that are currently eating are easier to find in the Universe, as the doomed space material shines brightly before it disappears forever into the monster’s mouth. Some galaxies that contain this type of Super-massive Black Hole are marked with red crosses in the picture above.
