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?
