One other thing. The author seems to be analogizing the hyperdrive to a traversable wormhole when he brings up black holes. Perhaps he should just use that instead of invoking tachyons. After all, that's what I assumed the hyperdrive was, and I imagine as you pass along the geodesic from one mouth to the next you'd see something distort outside, which should give us an idea of the shape of the mouths.

Relativistic effects are be severe. Observers in realspace watching the ship pass would see it through severe and bizarre relativistic distortions, but for the starship occupants the entire galaxy seems to be rushing past with the same sort of distortion.

Kaleidoscopic splotches appear to sweep past the starship as if they were features outside the walls of a tubular tunnel down which the ship travels. This vista is actually due to the galactic starfield. The splotches are related to local astronomical inhomogeneities like star clusters and emptier spaces. They appear to fly past at different visual distances because of the starfield itself is three-dimensional. The fact that they never appear to pass close to the starship is simply because sane pilots always plot courses which avoid obstacles.

Experienced hyperspace scouts may have a limited skill in interpreting the swirls of hyperspace in terms of realspace star clusters and nebulae. Thus with good reflexes and good luck new jump routes can be safely explored. It was in this way that young sibling scouts Gav and Jori Daragon accidentally discovered a fast route between the known worlds of the Old Republic and the isolated Sith Empire. Manual hyperspace scouting is extremely dangerous and is usually performed by inexpensive probe droids rather than crewed vessels.

All SW ships has relativistic shielding to protect against things like this so the causality issue doesn't come into affect for SW FTL travel.

Isn't most of the innovative work on this site driven partially by a disgust for ST's poor storytelling and poor use of science and engineering concepts?
