"This category [science fiction] excludes rocket ships that make U-turns, serpent men of Neptune that lust after human maidens, and stories by authors who flunked their Boy Scout merit badge tests in descriptive astronomy."

| 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. |

'The world ... is drenched in unfamiliar information all the way to the horizon.'
'He saw one hiss by him as he rounded the corner, trailing a short whip antenna...'
'It may be organic damage. It may be permanent. Time'll tell, and only after you are off Substance D for a long while.'
It's the polite thing to do, and has been the polite thing to do for about four generations.
