No, dark matter is definitely not the inverse of regular matter. Dark matter is spread unevenly through the universe, and it's spread in a pretty similar (but still notably different) way to the spread of regular matter. For example, where you have galaxies with lots of regular matter there is also lots of dark matter, but it has a slightly different distribution. You seem to be imagining something cool, but not something that bears much resemblance to our universe.

Thanks for that! I realize it was a pretty n00b question, I appreciate you taking the time. :)

So there could be dark matter stars, and dark matter planets? Dark-matter supernovas? Perhaps even in the same locations? Or is this strictly a galaxy-scale phenomenon and not an immediately local phenomenon?

That's part of the problem with dark matter theory, isn't it? Theory predicts even and well distributed dark matter anti-particles, yet there isn't in the observable universe...

I'm not sure what you're referring to. I don't think the theoretical problems around antimatter are any worse for dark matter than they are for baryonic matter.
