"Science fiction writers, I am sorry to say, really do not know anything. We can't talk about science, because our knowledge of it is limited and unofficial, and usually our fiction is dreadful."
- Philip K. Dick

Alderson Point  
  One end of a tramline, a path between stars that can be traversed using a hyperdrive engine.  

Also known at the "Crazy Eddie" point. The idea presented here is that there are pairs of points widely distant in space that are connected outside of normal space. A vessel equipped with the Alderson Drive can take advantage of this pair of points, moving from one to another without traversing the space in between.

I've been on trips where it was faster to drive over to another Alderson point, make a Jump, move around in the new system, Jump somewhere else, keep doing that until you come back to the original system at a different place - do all that and it would still be faster than merely to sail across the original system in normal space.
