About stuff (which can be material or immaterial), desire (resulting from need or greed) and collapse. A collapse happens when desire exceeds stuff and stuff runs out. In the terms of this book, infinity is crossed. The collapse can be visualized as an asymptotic curve jumping nothing. If the stuff is important, the collapse is important. There are two ways to avoid a collapse - reduce demand or increase the supply of stuff. Crossing Infinity "distills" six books about this subject. To distill a book is to capture its essence. The books distilled are (1) Great Disruption, (2)Upside of Down, (3) Coming Apart, (4) Collapse, (5) Black Swan and (6) Flat Earth.
