I think I am starting to get it some … but just enough to know I don’t really … 
Thanks very much.
Correct me if I’m wrong, but I think that the muons and anti-muons that reach the Earth’s surface are secondary products created when high energy cosmic rays strike the upper atmosphere and various processes create the particles that actually reach the ground.
Yep, that’s correct.

Well, we can be sure antimatter is a power so great, it can only be used for good or evil.
I happened to read Frank Close’s Antimatter (Oxford Landmark Science) and immediately thought of this thread.
Close is a working physicist (or was; he may be retired now) who started writing books for the popular audience. Antimatter is short and math-free, but it talks about the subject in detail and from many angles. Along the way it addresses and answers many of the questions in this thread.
If any of you want a good quick primer on the issues, I’d recommend it.
