We know pretty well what matter is and how it interacts with the others.

Dark matter interacts through gravity but not light. Beyond that I haven’t heard much else.

And lastly anti-matter has an opposite charge and interacts with matter through annihilation. I think I remember hearing that it would react with dark matter the same way.

So my question is, does anti-dark matter exist, and what are it’s properties?

    So if there were a small “lump” of dark matter in front of me, it would be invisible, and I could pass through it (and it through me) without noticing it was there?

      Right. It’s estimated that there’s about an asteroid’s worth of dark matter passing through the solar system at any given moment, so it’s possible that that has already happened.
