" I sometimes suspect that we're seeing something in the Internet as significant as the birth of cities. It's really something new, it's a new kind of civilization."
- William Gibson

Collapsar Jump  
  Travel between collapsed stars in no time at all.  

Twelve years before, when I was ten years old, they had discovered the collapsar jump. Just fling an object at a collapsar with sufficient speed, and it pops out in some other part of the galaxy. It didn't take long to figure out the formula that predicted where it would come out: it travels along the same "line" (actually an Einstein geodesic) it would have followed if the collapsar hadn't been in the way - until it reaches another collapsar field, whereupon it reappears, repelled with the same speed at which it approached the original collapsar. Travel time between the two collapsars ... exactly zero.
