"...the space defense initiative drove the USSR bankrupt, and it originated at my house in Tarzana."
- Larry Niven

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.
From The Mote in God's Eye, by Larry Niven (w/J. Pournelle).
Published by Simon & Schuster in 1974
