The Antimatter Particles

In general, if you have a particle and you flip all of its charges, the charge, the hyper charge and the color, then you get the antimatter version of that particle. And it's part of this beautiful trend in the universe that we have these symmetries. We just don't really understand it. It might be that positrons and electrons are actually built out of the same bits just organized in different ways to create muon. That would be fascinating.
