Supermassive black holes are big (yes, that's why it's called supermassive and not just kindamassive), and the biggest can have a mass equivalent of 10 billion Suns.

Most galaxies, if not all, are thought to have a supermassive black hole at their center, our own Milky Way galaxy included. Their presence poses a giant question: how do they feed?

Scientists may have found a clue by observing the feeding habits of smaller black holes (but still massive; although they still aren't called kindamassive black holes for some reason).

By observing actively feeding black holes, they determined that when it comes to their feeding habits, size doesn't matter. Well, it does, in a sense that they eat an amount relative to their size, but what they found is that they feed in the same way.

Black holes that are located in the center of galaxies feed on gas from the immediate region, while smaller black holes are usually found feeding on a single star. Whatever they feed on though, it seems that all of them feed in the same way.

One scientist explains it this way: "They don't seem to care too much where they get their food from." So there you have it. In the center of every galaxy is a supermassive black hole that grabs at anything it can, with the same table manners as the smaller folk.
