Talk:He Fell into a Dark Hole

Alderson limitations are not unusual
The second paragraph of the Background section of this article states that, "...However, unlike most science fiction jump drives, these [Alderson force] jumps are limited so a ship can only jump from an Alderson Point, a certain location in space. Ships can only travel from and to these points.''

This is far from true. There are many examples in science fiction of starship drives that only function between a limited collection of fixed points, either constructed (as jumpgates), or naturally occurring (and sometimes given fanciful names). To give just two instances: "Horst congruencies" in Starman Jones by Robert A. Heinlein, and "wormhole junctions" in Honor Harrington by David Weber.
