_The Elegant Universe_, Brian Greene. He portrays the problem, IIRC, of particle interactions, describing how a pair of "loops" would interact in a way different from two particles -- they'd join for a while, forming one loop with different properties, and then separate once again into individual loops. Since we see this as a point-particle interaction, my understanding is that we have a hard time determining when or where the interaction actually takes place.
Unfortunately the book is, like 99 44/100% of my life, in storage. So I can't dig up the reference or backcheck it. :\
And Greene is obviously a partisan, so whatever alternate explanations exist might get short shrift in his own arguments.
Nova/PBS did a program a while back:

But I don't recall this part of it being discussed. Maybe it was deemed too deep for the audience. Or too abstract!
