I'm not surprised that there are some mysteries out there. There are many, many billions of galaxies in the observable Universe. We haven't have a
chance to look at more than a tiny, insignificant fraction of those galaxies. We look at a few hundred or a few thousand, and see some trends or some
similarities, but it would be unwise to try to generalize about galaxies in general from those few observations. It's kind of like trying to make
generalizations about humanity, based on what you know about a couple dozen people.
It seems to me that out of all these galaxies, we're going to find a whole lot that scientists find very puzzling. I would guess that when
scientists have some notion about how galaxies work, they'll keep on finding different galaxies that blow their theories out of the water. But
that's how we learn about this stuff - keep finding things that shake up our notions of how things work.
