I haven't the time for a real post on this subject, but suffice it to
say that the use of Wormholes is NOT a good idea in explaining Traveller
Jumps. I went over the physics involved with a good friend who is also
(a) a gamer and (b) a General Relativist and ex-student of Ted Newman
(as in Newman/Penrose Black Hole Theory, Newman/Penrose/Chandrashekar,
etc.). We worked out what would happen to a star system that had a
wormhole opened up anywhere near the primary or one of the planets.
The results were spectacular, but not very pretty.
