Q and A of the Day: Anti-Dark Matter?

Since we've had a couple of stories on dark matter recently, we wanted to feature some Q and A's we've received on the topic over the years.

Q: Is it possible for the existence of an 'anti-dark matter?' It was long predicted for the existence of anti-matter in theory so it seems plausible to me.

A: It depends on what dark matter is. If it is slow moving dark particles as many theorists predict, then one could assume there would be anti-particles. However, we would then have to explain why there are so many more dark matter particles than anti-dark matter particles (the same problem we are faced with for matter and anti-matter) or explain where the anti particles are hidden.
