Evil Twin[change source]
I'm not sure if referring to antimatter as the evil twin of matter is the metaphor that best describes the relationship between these two types of matter. Perhaps "identical twin" would be better... no, but something better must be written in here. We can't exactly impose morals on matter. I'll leave it up to you the author of this section.
Wow! This article is way off from Wikipedia's standards, in terms of writing style, citations, etc. Not that I really mind - it's nice to have some colorful writing once in a while. Don't be surprised though when the no-fun police come!
