[pmrid (Peter)]

Here is the question that demonstrates my ignorance. Well, so be it. The known cosmos is said to contain 100 billion galaxies each with hundreds of billions of stars whirling around within their separate gravitational systems. Between the galaxies, dark matter, perhaps, stray gas clouds like Smith's Cloud, but what about stars? Are there stars either sole or in small clusters in the void between galaxies? Or do stars only form and remain within galaxies?
