		If you want to learn about the origins, please read Bible. WTF? If 
there is something you want to say, say it. I wasted my time reading the 
abstract of the first paper, and there is no mention of rifts. I don't 
think that this woman knows what she is talking about, but hey, she did 
some research, she wrote a paper about it, so everybody who does this 
knows the things, in your world. Well, not in mine.
