Yes.

Do super massive black holes ever combine to form a singular black hole?

Amazing!! many thanks

that's an amazing info

Yes, there are stars that are not in galaxies; [url=http://apod.nasa.gov/apod/ap020119.html]this APOD[/url] discusses them, and [url=http://xxx.lanl.gov/abs/astro-ph/9801228]here's a research paper[/url] on them.

Frame 12: comparing distance between galaxies and distance between starts in a galaxy, I ask: are there random stars between galaxies?

Stars within a galaxy like our own almost never collide with each other. Galaxies themselves, however, run into each other all the time. What's more, when the Universe was younger and smaller, they ran into each other more often. In this talk, Dr. Knop gives an overview of the sorts of things we see observationally when galaxies run into each other, causing not only the beautiful cosmic collisions that we've seen images of, but also triggering huge bursts of star formation and even tremendous activity at the nucleus of those galaxies.

Dr. Knop will answer a selection of questions posted by July 8, 2012.
