Probably my favorite part of The Enlightening was one of the last things that came to me through the course of my endeavors, which is the matter/ anti-matter discrepancy in our universe. The solution is so perfect (though admittedly rather mind-blowing) that I have little doubt it is correct. In addition to this list of ten things you might not know about anti-matter, you may want to check out Chapter 36 of The Enlightening, where I describe the ultimate mega large-scale structure, based upon the crystalline structure of Polonium, strangely enough.
